混合RF/FSO协作中继系统中HPA非线性和IQ不平衡联合作用下的时间CSI相关性

Temporal CSI Correlation in Mixed RF/FSO Cooperative Relaying Systems Under Joint Effects of HPA Nonlinearities and IQ Imbalance

Elyes Balti, Neji Mensi, Danda B. Rawat

摘要:

本文分析了具有多个中继的RF/FSO混合系统的性能。为了选择最好的中继,我们采用部分中继选择与过时的CSI,其中我们调查的信道的时间相关性的影响。与绝大多数的工作,我们介绍了损害的继电器和目的地,我们比较传统的RF中继系统的性能。我们进一步推导出中断概率和遍历容量的表达式,以及解压缩工程见解系统的鲁棒性的界限。

英文摘要:

In this paper, we present the performance analysis of mixed RF/FSO system with multiple relays. To select the best relay, we adopt partial relay selection with outdated CSI wherein we investigate the effect of the temporal correlation of the channels. Unlike the vast majority of work, we introduce the impairments to the relays and the destination and we compare the performance against conventional RF relaying systems. We further derive the expressions of the outage probability and the ergodic capacity as well as the bounds to unpack engineering insights into the system robustness.
