摘要

本文提出了调制分集作为无线网络无编码协作通信的候选分集方案。给出了该方案在加性高斯白噪声(AWGN)存在下的Nakagami-m衰落信道中的性能分析。推导了M-ary相移键控(MPSK)调制方案的平均误码率(Pb)和平均符号误码率(Ps)的上界。结果表明,与传统的协作通信系统相比,采用调制分集的系统能够在误码率为10−4的情况下提供5db的性能改进。我们引入了一个功率分配因子,并证明了功率均等分配并不是最优解。此外,我们还分析了不同的旋转角度和功率分配对系统性能的影响。

Modulation diversity benefits in cooperative communications
In this paper we propose modulation diversity as a candidate diversity scheme for uncoded cooperative communication in wireless networks with decode-and-forward (DF) communication protocol. A performance analysis of such a scheme in Nakagami-m fading channels in the presence of additive white Gaussian noise (AWGN) is presented. An upper bound on the average probability of bit error (Pb) and average probability of symbol error (Ps) is derived for M-ary phase shift keying (MPSK) modulation schemes. It is shown that the system employing employing modulation diversity is able to provide a performance improvement of 5 dB at a bit error rate of 10−4 as compared to the conventional cooperative communication systems. We introduce a power allocation factor and show that equal power allocation is not the optimal solution. Furthermore, we also analyze the effect of different rotation angles and power allocation on the system performance.
