Communication is the modus operandi of transitory on information at a distance. As communication technologies gaining new dimensions, design and development of various protocols came into existence in couple of years. As per the current challenges of this term paper, we focused the scope and strength of quasi - orthogonal block codes (QOSTBCs) for NAKAGAMI channels. QOSTBCs are used with 3 time slots and three transmitted symbol using two transmit antennas. We are proposing 2 new QOSTBC code for Nakagami channels of this paper. Information is encoded by space-time block code and the information which is encoded, crack into n streams which are broadcasted by means of n broadcast antennas simultaneously. With the help of Maximum -Likelihood (ML) decoding detection codes can be decoded. So we can achieve better symbol error rate (SER) performance for offering QOSTBCs codes which have two transmit antennas and 3 time slots. The basic observable fact which decides reliable wireless transmission is time varying multipath fading. In this phenomena which make tether less transmission a challenge to compare fiber, coaxial cable, line of sight microwave for even satellite transmission.
通信是一种远距离信息传递的方式。随着通信技术获得新的维度,各种协议的设计和开发在几年内出现。根据本学期论文当前的挑战,我们重点研究了NAKAGAMI信道的准正交分组码(qostbc)的范围和强度。qostbc使用3个时隙和3个发射符号,使用两个发射天线。本文针对中上频道提出了2个新的QOSTBC代码。信息采用空时分组码进行编码,编码后的信息分成n个流,通过n个广播天线同时广播。在最大似然(ML)解码的帮助下,检测码可以被解码。因此,提供具有两个发射天线和三个时隙的qostbc码可以获得更好的符号误码率(SER)性能。时变多径衰落是决定无线传输可靠性的基本可观测事实。在这种现象下,无系绳传输比光纤、同轴电缆、视线微波甚至卫星传输都是一个挑战。

Pub Date : 2015-11-01 DOI: 10.1109/ICCN.2015.49

Mobile ad-hoc networks are spontaneous, on the fly, self adaptive networks. Every mobile node acts as route. Data is transmitted from host to destination through an ever changing network topology. In recent day's scenario multimedia streaming one of the important challenging tasks in Mobile ad hoc network (MANET) as it affects the Quality-Of-Services (QOS) of the network as it needs more bandwidth for smooth transmission of data. The QOS constraints of the network that includes minimum delay, maximum bandwidth and effective throughput for real time multimedia streaming needs to be enhanced. Ad-hoc on demand Distance Vector Multipath routing (AOMDV) protocol is used on Mac layer or in network layer for frequent and constant streaming of audio, video and text type of data. This work proposes a new approach of data compression with Ad-hoc on demand multipath distance vector (AOMDVc) to enhance the QOS of the network. Simulations were carried out by Network simulator tool (NS2) and measure the effective minimization of end to end delay and improvement of throughput of the network and results were compared with existing techniques. Results clearly exhibit the performance of the proposed approach over the existing protocols.
移动自组织网络是自发的、动态的、自适应的网络。每个移动节点都充当路由。数据通过不断变化的网络拓扑从主机传输到目的地。多媒体流传输是当前移动自组网(MANET)中具有挑战性的重要任务之一,因为它需要更多的带宽来保证数据的流畅传输,从而影响网络的服务质量(QOS)。网络的QOS约束包括最小延迟、最大带宽和实时多媒体流的有效吞吐量需要得到增强。AOMDV (Ad-hoc on demand Distance Vector Multipath routing)协议用于Mac层或网络层,用于频繁和持续的音频、视频和文本类型数据流。本文提出了一种基于Ad-hoc随需应变多路径距离矢量(AOMDVc)的数据压缩新方法,以提高网络的QOS。利用网络仿真工具(NS2)进行了仿真,测量了有效地最小化端到端延迟和提高网络吞吐量,并将结果与现有技术进行了比较。结果清楚地显示了所提出的方法优于现有协议的性能。

In this world of e-technology, two users/systems requires to authenticate each other before exchanging the information. For this, there are numerous schemes proposed and analyzed for authentication. Indeed, in 2013, Chang et al.'s proposed an efficient untraceable dynamic identity system based on remote user authentication and claimed that the scheme is secure against various attack. In opposition, in this paper we have identified that Chang et al.'s scheme is vulnerably susceptible to the attacks like Plain Text, Smart Card Lost, Denial of Service and Parallel Session.

Data exchanging on the roads are becoming more and more interesting, as the number of vehicles equipped with computing technologies and wireless communication devices are poised to increase dramatically. Communications between vehicles (V2V) and Vehicle to Infrastructure (V2I) is becoming a promising field of research and we are moving closer to the vision of intelligent transportation systems (ITS). The more challenging in vehicular networks, as the nodes can move at high speed in a wide area surrounded of buildings and many other architectural structures which can in turn affect the propagation of the radio signal. As a consequence, we introduce an innovative method based on clustering, using junction, graph theory, security & cooperation in this paper, exploits the collaboration among vehicles to quickly disseminate information on a wide area. We would like to mainly focus on the performance analysis of the protocol in city scenarios via simulation using NS2 simulator.

In this paper we have present and discussed the the Resonant Frequency (RF) and L-band systems providing a low insertion loss within the pass band and a large attenuation in the stop band. It uses the RFID tags backscatter responses. By interrogating different tag with a multi frequency signals it is possible to detect the variations in the magnitude and phase of the backscattered tag signal and decode it. The frequency signature based system is the first of its kind to use both amplitude and phase spectral signature backscatter to represent data. The above synthesize reduce the redundancy because the tags are connected with their own memory not with the copied magnitude and shared the existence which reduces the cost. This method provides us that parameter which shows the accurate attenuation parameter otherwise we fill with different parameter which is non-redundant based on different. As of late band pass channels have drawn a considerable measure of consideration. The outline of broadband microwave channel comprising of parallel-coupled lines as a rule has the acknowledgment issue of extremely slender coupled-line holes. So we have proposed a Multiresonators mechanism so that the conductive material is filled with predefined dimensions and then non redundant design procedure on that system is applied for achieving higher gain and lower error rates.
在本文中,我们提出并讨论了谐振频率(RF)和l波段系统,在通带内提供低插入损耗,在阻带内提供大衰减。它使用RFID标签反向散射响应。通过用多频信号询问不同的标签,可以检测后向散射标签信号的幅度和相位变化并对其进行解码。基于频率特征的系统是同类中第一个使用振幅和相位谱特征反向散射来表示数据的系统。上述综合减少了冗余,因为标签与自己的内存连接,而不是与复制的大小和共享的存在,从而降低了成本。该方法为我们提供了显示准确衰减参数的参数,否则我们会根据不同的参数填充不同的非冗余参数。最近,带通信道引起了相当大的关注。由平行耦合线组成的宽带微波信道的轮廓通常存在极细耦合线孔的确认问题。因此,我们提出了一种多谐振器机制,使导电材料充满预定的尺寸,然后在该系统上应用非冗余设计程序,以实现更高的增益和更低的错误率。

High datarate rate regulated 4D 8PSK-TCM implementation in FPGA for satellite 卫星高数据速率可调4D 8PSK-TCM的FPGA实现

With the increase in camera resolution or usage of SAR payload in remote sensing satellite, demand for high data rate transmission has increased in a given bandwidth. This has also forced to use higher modulation like 8 PSK over QPSK to accommodate higher data rate in the same bandwidth. A typical usage is 1.2Gbps data rate transmission scheme using 8PSK dual polarization in x-Band, having bandwidth of 375Mhz. Higher modulation scheme demands higher power to maintain the link margin. Alternative to the higher power is to use a suitable channel coding scheme. 4D 8PSK-TCM is a channel coding scheme suitable for 8PSK modulation [1]. The coding scheme supports Spectral Efficiencies of 2, 2.25, 2.5 & 2.75 bits/channel-symbol. Challenges exist in implementation of these different code rates in a single architecture as it demands rate buffer implementation to provide seamless transmission that is difficult to realize without the use of FPGA. The paper addresses the difficulties in implementation especially when the 4D 8PSK-TCM module is inserted in Data-link layer. The solution to these difficulties is implementation of a suitable rate regulator for various code rate of 4D 8PSK-TCM in FPGA for high datarate (~ 600Mbps) application. The paper also addresses 4D-TCM usages in data link layer of satellite transmission system.
随着遥感卫星相机分辨率的提高或SAR有效载荷的使用,在给定带宽下对高数据速率传输的需求增加。这也迫使在QPSK上使用更高的调制,如8 PSK,以适应相同带宽下更高的数据速率。典型的使用是在x波段使用8PSK双极化的1.2Gbps数据速率传输方案,带宽为375Mhz。更高的调制方案需要更高的功率来维持链路余量。替代更高的功率是使用合适的信道编码方案。4D 8PSK- tcm是一种适合8PSK调制的信道编码方案[1]。编码方案支持2、2.25、2.5和2.75比特/信道符号的频谱效率。在单一架构中实现这些不同的码率存在挑战,因为它需要速率缓冲实现来提供无缝传输,而不使用FPGA很难实现。本文论述了在数据链路层插入4D 8PSK-TCM模块时实现中的困难。解决这些困难的方法是在FPGA上实现适合4D 8PSK-TCM各种码率的速率调节器,用于高数据速率(~ 600Mbps)应用。本文还讨论了4D-TCM在卫星传输系统数据链路层中的应用。

A typical usage is 1.2Gbps data rate transmission scheme using 8PSK dual polarization in x-Band, having bandwidth of 375Mhz. Higher modulation scheme demands higher power to maintain the link margin. Alternative to the higher power is to use a suitable channel coding scheme. 4D 8PSK-TCM is a channel coding scheme suitable for 8PSK modulation [1]. The coding scheme supports Spectral Efficiencies of 2, 2.25, 2.5 & 2.75 bits/channel-symbol. Challenges exist in implementation of these different code rates in a single architecture as it demands rate buffer implementation to provide seamless transmission that is difficult to realize without the use of FPGA. The paper addresses the difficulties in implementation especially when the 4D 8PSK-TCM module is inserted in Data-link layer. The solution to these difficulties is implementation of a suitable rate regulator for various code rate of 4D 8PSK-TCM in FPGA for high datarate (~ 600Mbps) application. The paper also addresses 4D-TCM usages in data link layer of satellite transmission system.","PeriodicalId":431743,"journal":{"name":"2015 International Conference on Communication Networks (ICCN)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114903136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents the design and analysis of a 2:1 multiplexer. The conventional circuit of 2:1 multiplexer(MUX) is used for the calculation of different parameters like power consumption, noise, delay, leakage power, etc. The multiplexer designed in this paper is suitable for low-power applications and works on very low supply voltage. Multiplexer is a digital circuit, it consists of 2N input and has n select line which are used to select the input line to transmit to the output. The multiplexer are used to expand the measure of information that can be sent over the system of a sure measure of time and bandwidth. Multiplexer comprises of multiple input signals and gives a single output switch. In this paper, a novel FinFET technique is used for the reduction of leakage power. The parameters of the conventional circuit and FinFET are compared and the performance of the multiplexer circuit is increased. The proposed multiplexer works on supply voltage of 0.7V. The design and simulation of FinFET based 2:1 multiplexer is done by using 45nm technology at cadence virtuoso version 6.1 platform.
