摘要 针对协作分集系统中放大转发协议存在的噪声放大问题,提出了一种增强型选择放大转发机会协作分集协议.该协议首先在多个中继中选择最优的中继,然后目的节点对源节点第1步广播的信息做出成功、半成功和失败3种反馈,源节点和最优中继节点根据反馈信息分别采取非协作传输、源节点重传和中继放大转发3种方式,由于加入了源节点重传,因此减少了中继放大转发次数及噪声的放大.理论分析和仿真结果表明,当中断概率为10-3、中继个数为4时,与增强型放大转发机会协作分集协议相比,该协议约有0.4dB的信噪比增益,并且达到了和理想分布式空时码相同的分集-复用折中. An improved cooperative diversity protocol named incremental selection amplify forward opportunistic relaying（ISAFOR）is proposed to improve the noise amplification problem in amplify-forward protocol.The new scheme first chooses the best relay among relays.The destination sends three types of feedback when it receives the information which is sent from the source node in the first step.The three types of feedback are success,half-success and failure.Then the protocol will work with 3 transmissions：non-cooperative transmission,retransmission and amplify forwarding.It is the retransmission by the source that the new protocol reduces the times of amplify-forwarding and the noise amplification.Theoretical analysis,simulation results and comparisons with the incremental amplify forward opportunistic relaying show that when the number of relays is 4 and the outage probability is 10-3,the proposed protocol achieves about 0.4dB signal to noise ratio gain and obtains the same diversity-multiplexing as ideal distributed space-time code.
