The traditional multiple-station direct position determination method suffers location accuracy loss and source resolution degradation for the lack of position information fusion of raw data. And an information fusion direct position determination method based on Wishart random matrix asymptotic distribution theory is proposed to overcome the above-mentioned shortcomings. Firstly, the information fusion direct position determination model is established via fusing raw data of each station. Then the new cost function containing eigenspace is constructed with theory of Wishart random matrix asymptotic distribution. Finally, the target location estimation is obtained by two-dimensional geographic grid search. Furthermore, the Cramer-Rao bound of the new model is derived. Compared with the original method, the proposed method performs much better in location accuracy and source resolution by simulations. And it frequently outperforms the information fusion direct position determination method with the cost function only containing noise subspace, under scenarios of low SNR and snapshot deficiency. Its performance has been greatly improved at the expense of lower complexity.

With the growth of wireless communication services, large base stations will not only produce a lot of electromagnetic radiation, but also bring huge energy consumption, resulting in a large number of greenhouse gases. The fifth generation mobile communication will deploy the macro base stations and the micro base stations in multi-layer heterogeneous network to enhance the system network performance, reducing the negative impact of above-mentioned factors. According to the theory of cell communication, in this paper, by adding the micro base stations distributed in different grid modes in the surrounding area of the macro base station, the purpose is to maximize the total area covered by the base stations in the cell under the condition that the total power consumption of the base stations is not increased.

The Service Function Chain (SFC) is a mechanism which transmit packets through different services in order. With Software Defined Networking (SDN) and Network Function Virtualization (NFV), network services can be flexible deployed on the middleboxes. However, end-to-end transmission delay of the SFC will influence the time delay in a network, which is a key indicator to the performance of a network. One way to decrease transmission delay is to optimize the deployed sequence of service middleboxes. In this paper, we put forward a Middlebox Placement Optimization (MPO) algorithm. Different from the previous works, the MPO algorithm fully utilizes the flexibility and dynamicity provided by SDN and NFV, and can dynamically deploy the sequence of services in the SFC to adapt real-time changing service characters. Simulation results show that MPO can reduce the end-to-end delay by an average of 30 percent comparing with the traditional First Construction First Placement (FCFP) algorithm.
SFC (Service Function Chain)是一种按顺序在不同业务之间传输数据包的机制。通过软件定义网络(SDN)和网络功能虚拟化(NFV)，网络业务可以灵活地部署在中间件上。但是SFC的端到端传输延迟会影响网络的时延，而时延是网络性能的一个关键指标。减少传输延迟的一种方法是优化业务中间盒的部署顺序。本文提出了一种中间盒放置优化算法(MPO)。与以往的工作不同，MPO算法充分利用了SDN和NFV提供的灵活性和动态性，可以在SFC中动态部署业务序列，以适应实时变化的业务特性。仿真结果表明，与传统的FCFP (First Construction First Placement)算法相比，MPO算法可将端到端延迟平均降低30%。

Wireless mesh networks (WMNs) have been broadly accepted as a high-performance and low-cost solution to last-mile broadband internet access. But it is still difficult to reach seamless roaming. This paper proposes a software-defined wireless mesh network (SD-WMN) providing seamless roaming services. The advantages of the SD-WMN include: (1) reducing the handover latency and the number of lost packets by a quick disconnect mechanism; (2) updating the node flow table in time from a logically-centralized controller. Experiments taken in the streaming media VOD system have proved the feasibility and efficiency of SD-WMN.

Encryption is the most important method to enhance security of network transmitting. SDN (Software Defined Networking) Security Transmission Service can provide multi-connection transmitting service, which scatters data to multiple network connections for transmission so that data on different connections are isolated from each other. Based on the service, encrypting the isolated data prevents overall data from intercepted and deciphered. In the above scenario, we propose an encryption algorithm that uses the data themselves as encryption keys, and use the data isolation effect of multi-connection transmission to distribute the encrypted ciphertext to different network transmission paths, which is equivalent to using a rather random sequence as an encryption key for each data fragment without sharp increase in transmitting data, so that data transmitted on every connection are ensured to be safe. After compared with other encryption algorithms such as DES, AES and RSA, it is proved that in the multi-connection transmitting scenario this algorithm has better encryption effect and operating efficiency, which provides an effective guarantee for network security.
加密是提高网络传输安全性的重要手段。SDN (Software Defined Networking)安全传输服务可以提供多连接传输服务，将数据分散到多个网络连接进行传输，使不同连接上的数据相互隔离。根据服务的不同，对隔离的数据进行加密可以防止整体数据被拦截和解密。在上述场景中，我们提出了一种以数据本身作为加密密钥的加密算法，利用多连接传输的数据隔离效应，将加密后的密文分发到不同的网络传输路径上，相当于在传输数据量没有急剧增加的情况下，对每个数据片段使用一个相当随机的序列作为加密密钥，从而保证在每个连接上传输的数据是安全的。通过与DES、AES、RSA等其他加密算法的比较，证明了该算法在多连接传输场景下具有更好的加密效果和运行效率，为网络安全提供了有效的保障。

The narrow bandwidth of microstrip antenna is one of the important features that restrict its wide usage. An enhanced bandwidth design technique is presented in this paper. By loading different shapes of slots on parastic patch, the broad-band microstrip antennas is obtained. Utilizing this design technique, broad-band microstrip antennas have been proposed. To confirm the applicability of the method for the designs of antennas at C-band, simulations and experiments have been carried out. The measured results show that the proposed antennas have a relative bandwidth of up to 13%, and have a broad-band antenna gain no less than 6dB.

This paper presents the design of a compact planar inverted-F antenna (PIFA) with reconfigurable dual resonance frequency of 800 MHz and 1.4 GHz, and switchable horizontal and vertical polarization for mobile devices. PIN diodes are used to electronically control the antenna's electrical path width so as to achieve the desired resonance frequencies. The narrower the electrical path, the higher the resonance frequency. The antenna comprises a coupled parasitic shorted strip and feeding strip. By controlling the ON/OFF states of two PIN diodes, four operation modes from two frequencies and two polarizations can be achieved. The proposed antenna has a gain of 3.7 dBi, efficiency of up to 92%, and a reflection coefficient of less than −10 dB over the resonant bands for both horizontal and vertical polarizations.

In contrast to conventional multiple-input-multiple-output (MIMO) systems, precoding in millimeter wave (mmWave) massive MIMO is envisioned to achieve considerable capacity improvement, but at the cost of highly hardware complexity. As a cost-effective alternative, hybrid digital-analog beamforming has drawn considerable attention. In most conventional theoretical researches, ignoring practical implementation, perfect channel state information (CSI) is always assumed. However, whether FDD or TDD, in hybrid beamforming architecture, it is extremely challenging for base station (BS) to obtain perfect CSI. In this paper, based on the channel reciprocity in TDD systems, we propose a novel hybrid digital-analog beamforming algorithm with uplink training to maximize the capacity performance. Owing to uplink training, the requirement of CSI at eNodeB to conduct hybrid beamforming is graciously avoided. With practical RF hardware and unit modulus constraints, the proposed scheme provides useful low-complexity solutions in practical hybrid beam-forming system designs. Simulation results validate the efficiency of the proposed scheme compared with some existing hybrid beamforming schemes.)

This paper investigates secure communications in fixed gain untrusted relay networks. Unlike the trusted relay, an untrusted relay may be an eavesdropper and also does not have the instantaneous channel state information (CSI) of the main link. We propose a destination aided secure transmission scheme. A closed-form of achievable secrecy rate of the proposed scheme is derived and the optimal power allocation between the information signal and jamming signal is also discussed. Simulations elaborately verify our theoretical results.

The time-varying feature of the spectrum for wireless communication countermeasure system is analyzed. And the mathematical model of the time-varying spectrum is proposed. With the help of adaptive filtering theory, the performance criteria of optimal spectrum sensing algorithm is proposed, in which the total error was composed by sensing error and lag error. The objective of the real-time spectrum sensing algorithm is to minimize the summation of sensing error and lag error. Finally, the proposed performance criterion was used to guide the channel estimation of intelligent frequency hopping communication system.
