摘要

提出了一种采用空间移位键控(SSK)调制和同步无线信息与功率传输(SWIPT)方案的协同通信系统。SWIPT可以消除中继对外部电源的需求,而SSK调制方案减少了信道间干扰,不需要天线间同步和射频链的数量。在多个转发中继和源节点到目的节点的直接链路的情况下,得到了平均误码率(ABEP)的上界表达式。进一步分析了ABEP在部分继电器选择操作中的应用。数值和计算机仿真结果表明,SSK调制与SWIPT相结合可以提高性能。

SSK Performance with SWIPT based Dual-Hop AF Relay over Rayleigh Fading
A cooperative communication system with space shift keying (SSK) modulation and simultaneous wireless information and power transfer (SWIPT) scheme is proposed. SWIPT can eliminate the need of external power supply at the relay whereas SSK modulation scheme reduces inter-channel interference, excludes inter antenna synchronization requirement and the number of radio frequency chains. An upper bound expression for the average bit error probability (ABEP) is obtained with multiple amplify-forward relays and a direct link from source node to destination node. Further, ABEP is analyzed for partial relay selection operation. Numerical and computer simulation results demonstrate performance improvement for SSK modulation combined with SWIPT.
