摘要

协作分集是无线系统中实现空间分集的一种很有前途的技术。本文分析了在瑞利衰落信道上采用自适应离散m -正交调幅(M-QAM)的基于信噪比的混合译码-放大-前传(HDAF)中继系统的中断概率和可实现的频谱效率。考虑了一种简单的三终端协同无线系统，目的端采用最大比组合技术。

On the performance evaluation of hybrid decode-amplify-forward relaying protocol with adaptive M-QAM modulation over Rayleigh fading channels

Cooperative diversity has been proposed as a promising technology to achieve spatial diversity in wireless systems. In this paper, we analyze the outage probability and achievable spectral efficiency of SNR-based hybrid decode-amplify-forward (HDAF) relaying system with Adaptive discrete M-ary Quadrature Amplitude Modulation (M-QAM) over Rayleigh Fading channels. We consider a simple cooperative wireless system with three terminals while maximum ratio combining (MRC) technique, is used at destination.
