摘　　要：提出了基于目的节点驱动的非再生选择合作系统。在独立非同分布的Rayleigh衰落下分析了该系统的BPSK误码率性能,并导出了闭式解。数值分析和仿真表明该选择合作方案实现了系统性能与目的节点的处理复杂度的良好折中,对减少目的节点接收机的信号处理功耗也很有好处。此外,仿真结果也验证了理论研究在中高SNR区近似分析的正确性。A non-regeneration cooperative system based on destination-driven for multi-hop wireless networks was proposed.The BER （bit error rate） performance of BPSK （binary phase-shift keying） for the proposed system was analyzed over independent and non-identically distributed （non-i.i.d） Rayleigh fading channels,and its close-form expression was derived.The theoretical analysis and simulation results show that the proposed system achieves a good tradeoff between the system performance and the processing complexity of the destination node,and is very helpful to reduce the power consumption the destination node.Otherwise,the simulation results also agree well the analysis results at medium and high SNR （signal to noise ratio） values.
