摘要:
通过考虑过时的信道状态信息对固定增益放大转发协作通信系统的性能影响展开研究。在假设所有信道服从独立同分布瑞利衰落条件下,率先推导出中继选择协作通信系统的接收信噪比的概率分布。由此,推导出中断概率、比特错误概率和平均信道容量的闭式表达式。数值分析表明,固定增益放大中继选择方案的性能受到中继节点数目、信道相关系数和端对端信噪比的影响。此外,所提方案比传统的机会选择方案反馈负载减少50%,能很好地实现复杂度与系统性能的折衷。
Abstract:
The impact of outdated Channel State Information(CSI)on the performance of fixed-gain Amplify-and-forward(AF)cooperative communication systems considering the partial relay selection schemes is studied. The closed-form expressions for the distribution of received Signal-to-Noise Ratio(SNR)in a relay-selection-assisted cooperative communications system are first derived, in which independent and identically distributed(i.i.d.)Rayleigh fading channels are assumed in each wireless link. After that, the theoretical closed-form expressions for outage probability, symbol error ratio, and average channel capacity are derived. Numerical analysis shows that the performance of fix-gain AF relay-selection scheme can be substantially influenced by parameters such as the number of relays, the channel correlation coefficient, and the end-to-end SNR. Furthermore, compared with the traditional opportunistic-selection scheme, the feedback burden of the proposed scheme will be reduced by 50%, which provides an excellent compromise between complexity and performances of the system.
