摘要

给出了在瑞利衰落环境和高信噪比条件下，有或无直接路径的双跳固定增益放大转发系统的中断概率(OP)和平均误差概率(AEP)的简单渐近表达式。我们表明，当不使用直接路径时，OP和EP都以log(SNR)/SNR衰减，而当使用直接路径时，OP和EP在高信噪比下以log(SNR)/SNR2衰减。

Asymptotic performance of dual-hop non-regenerative cooperative systems with or without direct path

We derive simple asymptotic expressions for the outage probability (OP) and the average error probability (AEP) of dual-hop fixed-gain amplify-and-forward relaying system with or without direct path in a Rayleigh fading environment and high signal-to-noise ration (SNR). We show that, when direct path is not utilized, both OP and EP decay as log(SNR)/SNR, whereas, when the direct path is utilized, OP and EP decay as log(SNR)/SNR2 at high SNRs.
