摘　　要：基于系统端到端信噪比的矩生成函数(MGF),分析了非再生(nonregenerative)协同通信系统在平坦衰落信道下的分集性能,并用计算机仿真证明了分析结果的正确性。分析结果表明,采用固定增益中继的双跳协同通信系统的分集阶数小于1。The diversity performance of a general cooperative transmission system with nonregenerative fixed gain relays in flat fading channels is analysed based on end to end SNR（signal-to-noise ration） of MGF（moment generation function）.Simulation is performed to verify the analysis result that the diversity order of the two-hop cooperative transmission systems with fixed gains is less than one.
