摘要

针对两跳多中继放大转发协同通信系统

分析了信道估计误差对系统性能的影响。考虑机会中继和全参与中继两种中继策略

分别推导了系统误码率的闭式表达式

并分析了不同信道估计质量阶数下的系统分集增益。平均信噪比损失率分析表明机会中继较全参与中继对信道估计误差更为敏感。仿真结果验证了理论分析。

Abstract

The impact of channel estimation errors on the performance for two-hop multi-relays assisted am-plify-and-forward（AF） cooperative communication systems was investigated.Closed-form expressions of the average symbol error rate

as well as the diversity gain under different channel estimation quality orders for both opportunistic re-laying（OPR） and all-participate relaying（APR） schemes were derived.Average signal-to-noise-ratio（SNR） gap ratio is investigated for the two types of cooperative communication systems

which lead to a conclusion that the OPR scheme is more susceptible to channel estimation errors than the APR scheme.Numerical results verify the theoretical analysis.
