    Performance analysis of multi-relay DF cooperative communication system based on directional antenna by Mingwei WANG, Huisheng ZHANG, Lixin LI, Lifeng HE

    Published 2016-06-01
    “…In order to achieve reliable communication in multi-relay cooperative communication,the directional antenna combining multi-relay cooperative communication system and optimal relay selection decode-and-forward cooperative strategy was presented.Firstly,the theoretical closed form of outage probability of the communication system using directional antenna operating in the three modes of DT-DR,DT-OR and OT-OR were presented.Then for three kinds mode,the collaboration communication system interrupt probability and signal-to-noise ratio,the number of relay nodes,the antenna gain channel fading efficiency and relationship between the channel capacity were analyzed in numerical simulation.These findings reveal that excellent performance of cooperative communication system with directional antennas could be achieved such as smaller outage probability and improved by best relay nodes and optimal power allocation coefficient.…”

    Scatterer information based indoor NLOS multiple base station cooperative localization algorithm by Liangbo XIE, Sheng LI, Mu ZHOU, Ze LI, Zengshan TIAN, Ya WANG, Changyou FU

    Published 2021-05-01
    “…In indoor environments, the localization accuracy of existing line of sight (LOS) solutions will deteriorate severely in non-line-of-sight (NLOS) environment.In order to solve this problem, an scatterer information based indoor NLOS multiple base stations cooperative localization algorithm was proposed, which could realize localization when no LOS path was available.Firstly, the target NLOS area and scatterer blur area were collaboratively determined through multiple AP and joint scene prior information.Secondly, the areas of scatterer were further constrained according to the angle of arrival.Then, an error minimization equation based on the differential time of flight was established by employing angle, scatterer and time.Finally, a hybrid algorithm using genetic algorithm and Levenberg Marquardt algorithm was proposed to solve the objective equation.Simulation and measurement results show that the proposed algorithm can localize the target with only NLOS paths.…”

    A cooperative control strategy for power quality based on parallel grid-connected converters by LIANG Xiaorui, LUO Yuhang, ZHANG Huaying, TU Chunming, LIU Huicong, ZHENG Yuting

    Published 2025-01-01
    “…However, existing methods tend to only consider grid-following (GFL) control and fail to fully utilize the control potential of multiple converters. In this paper, a cooperative control strategy for harmonic compensation and voltage drop suppression is proposed based on a parallel system of GFL and grid-forming (GFM) converters. …”

    Downlink and Uplink Cooperative Transmission for Primary Secrecy Based Cognitive Radio Sensor Networks by Dawei Wang, Pinyi Ren, Qinghe Du, Li Sun, Yichen Wang

    Published 2015-10-01
    “…Aiming at allocating more licensed spectrum to wireless sensor nodes (SNs) under the constraint of the information security requirement of the primary system, in this paper, we propose a cooperative relaying and jamming secure transmission (CRJS) scheme in which SNs will relay primary message and jam primary eavesdrop concurrently with SN's downlink and uplink information transmission in cognitive radio sensor networks (CRSNs). …”
