Abstract

Due to the non-ideal characteristics of the transceivers, there always exists some residual hardware impairments (RHIs) in practical communication systems, which could lead to degraded system performance. Therefore, in this study, we investigate wireless-powered relaying assisted underwater wireless optical communication-radio frequency systems in the context of RHIs. Specifically, considering the scenario that a multi-aperture and multi-antenna relay employs both a selection combining and a transmit antenna selection schemes to process the received and transmitted signals, we first obtain both the probability density function and cumulative distribution function of the instantaneous signal-to-interference-plus-noise ratio of the first link with RHIs. Next, utilizing those expressions as well as the Meijer’s-

G

and Fox’s-

H

functions, the analytical and asymptotic expressions of outage probability as well as analytical average bit error rate expressions are obtained. In addition, Monte-Carlo simulations are performed to check the accuracy of those obtained expressions.

具有残余硬件损伤的无线供电中继 SIMO-UWOC/MISO-RF 网络

由于收发器的非理想特性，实际通信系统中总会存在一些残余硬件损伤（RHIs），这可能会导致系统性能下降。因此，在本研究中，我们研究了 RHIs 背景下的无线供电中继辅助水下无线光通信-射频系统。具体来说，考虑到多孔径、多天线中继采用选择组合和发射天线选择两种方案来处理接收和发射信号的情况，我们首先得到了具有 RHIs 的第一链路的瞬时信号干扰加噪声比的概率密度函数和累积分布函数。然后，利用这些表达式以及 Meijer's-G 和 Fox's-H 函数，得到中断概率的分析和渐近表达式以及平均误码率的分析表达式。此外，还进行了蒙特卡洛模拟，以检验这些表达式的准确性。
