A new memory based LT encoding scheme is proposed to improve communication reliability and decrease latency at the same time. The robust Soliton distribution (RSD) is shifted as the output symbol degree distribution in the proposed method. The input symbol degree distribution is also changed based on memory. Analysis shows the proposed method has faster decoding convergence speed than the conventional memory based LT code. Simulation results validate the analysis and show BER performance. Compared with regular LT code and the conventional memory based LT code, the proposed method has better BER performance.

A new miniaturized triple-frequency microstrip antenna is proposed. The proposed antenna mainly consists of two circular rings, a circle, a horizontal rectangular strip, three vertical rectangular strips and a defected ground plane. The proposed antenna can generate three separate impedance bandwidths to cover all the 2.4/5.2/5.8GHz Bluetooth/WLAN (Wireless Local Area Network)/RFID (Radio Frequency Identification Devices) operating bands and the 2.5/ 3.5/5.5GHz WiMAX (Worldwide Interoperability for Microwave Access) operating bands. By adding a vertical rectangular strip and a circle along the microstrip direction, the antenna excites two resonant modes and is with miniaturized structure. Because of the introduction of the cambered ground plane with a circular defect, the third wide band with better impedance matching is obtained. Result shows the proposed antenna has good performance.

This paper presents a new fuzzy clustering algorithm to solve the problem that the fuzzy c-means (FCM) clustering algorithm has a poor accuracy of clustering. The adopted methodology used the minimum support tree principle to get the initial clustering center and augmented lagrange multiplier method to solve the problem of noise sensitive of the FCM algorithm. Besides, the Hopfield neural network is used to calculate the cluster center and complex synaptic neural network is used to obtain the membership grades. In the experiment, the proposed algorithm is simulated and compared with the commonly used clustering algorithm. The clustering accuracy is higher than that of other algorithms. The analysis proves that the algorithm has universal guiding significance in theory and engineering practice.

Design of complementary sequence for OFDM systems with vacant direct current subcarrier 具有直流空子载波的OFDM系统互补序列设计

Complementary pair has ideal aperiodic auto-correlation property and then may reduce the peak-to-mean envelope power ratio (PMEPR) of orthogonal frequency division multiplexing (OFDM) systems to 3dB. However, for some OFDM systems requiring vacant direct current (DC) subcarrier, the ideal aperiodic auto-correlation property of complementary pair will be damaged, which leads to the increased PMEPR. In this paper, the modified sequences are designed on the basis of zero-inserting operation and combination operation to original complementary pair, respectively. The proposed methods may maintain ideal aperiodic auto-correlation property of original complementary pair even if it is employed in OFDM systems with vacant DC subcarrier. Both theoretical analyses and simulation results show the availability of the presented algorithms, and the expectable PMEPR-3dB property may be obtained.
互补对具有理想的非周期自相关特性,可将正交频分复用(OFDM)系统的峰均包络功率比(PMEPR)降低到3dB。然而,对于某些需要直流空子载波的OFDM系统,会破坏互补对理想的非周期自相关特性,导致PMEPR增大。本文分别在对原互补对进行插入零运算和组合运算的基础上设计了改进序列。该方法即使应用于具有空直流子载波的OFDM系统中,也能保持原互补对理想的非周期自相关特性。理论分析和仿真结果均表明了所提算法的有效性,并可获得预期的PMEPR-3dB性能。

In this paper, a miniaturized, self-actuated, energy selective spatial filter is designed for achieving field intensity dependent electromagnetic (EM) protection in a working frequency band. The spatial filter is periodic with each unit loaded with four microwave nonlinear devices. The dimension of the unit is in size of λ/16 and is ultrathin. Structural design, mechanism of operation are presented and discussed. A full-wave simulation is carried out for obtaining the transmission characteristic of the spatial filter. Results show that the received field intensity by using the spatial filter can be well controlled with a variable power loss from 0.1 dB up to 24 dB, and the spatial filter has a stable transmission characteristic to different incident angles. Therefore, the spatial filter is able to distinguish small signals from strong incident waves and can be utilized in EM protection against high power microwaves.

To detect compromised sensor nodes in wireless sensor network, one main way is to detect their sensing data with the cooperation of their neighbor nodes because of spatial correlation. In most time, these neighbor nodes are equally treated. However these neighbor nodes are different in the view of temporal correlation. To address this, we discuss the differential cooperation of neighbor nodes. In this paper, we proposed distance-differential cooperation and correlation-differential cooperation, and discuss their advantage and disadvantage with the cases study. Our discussion shows that differential cooperation is capable of improving the capability of detecting compromised sensor nodes.

Image transmission issue with high entropy frames is a great challenge for joint source channel coding (JSCC) system based on double protograph low-density parity-check codes (DP-LDPC) due to its sensitivity to source statistics. Aiming at this question, we proposed an effective rate allocation scheme with the premise of unfixed total rate to allocate the source coding rate and channel coding rate for each frame based on source and channel characteristics. In this scheme, two kinds of objective utility function (OUF) models and corresponding rate allocation methods are provided, including the single objective utility function (SOUF) model with global search method and the multi-objective utility function (MOUF) model with fuzzy logic control (FLC) method. Simulation results indicate that both models are effective for DP-LDPC system with high entropy frames, and the MOUF model with FLC method has better adaptive capacity to time-varying channel and better balance on transmission efficiency, image quality and fairness of allocation. The proposed methods offer some new solutions for high entropy frame problem of DP-LDPC image transmission system.
高熵帧的图像传输问题是基于双原型低密度校验码(DP-LDPC)的联合信源信道编码(JSCC)系统的一大挑战,因为它对信源统计量非常敏感。针对这一问题,我们提出了一种有效的速率分配方案,在总速率不固定的前提下,根据信源和信道的特性对每帧进行源编码速率和信道编码速率的分配。该方案提供了两种目标效用函数(OUF)模型和相应的费率分配方法,包括采用全局搜索方法的单目标效用函数(SOUF)模型和采用模糊逻辑控制(FLC)方法的多目标效用函数(MOUF)模型。仿真结果表明,两种模型对具有高熵帧的DP-LDPC系统都是有效的,并且采用FLC方法的MOUF模型对时变信道具有更好的自适应能力,在传输效率、图像质量和分配公平性方面具有更好的平衡。所提出的方法为DP-LDPC图像传输系统的高熵帧问题提供了一些新的解决方案。

Service chain performance optimization based on middlebox deployment 基于中间盒部署的服务链性能优化
Pub Date : 2017-10-01 DOI: 10.1109/icct.2017.8359969

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%。

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.
