论文摘要
最近的研究提供了关于可重构智能表面（RIS）辅助系统在通用褪色通道上的性能的近似值，该系统与RIS不完善的相位补偿所致的相位噪声产生了相位噪声。在本文中，我们对RIS辅助的车辆通信系统的性能进行了精确的分析和上限，考虑了相位噪声，这些噪声与不对称褪色通道相对于不对称褪色通道进行了相干组合，并通过RIS元素反映的接收信号和来自源终端的直接传输。我们采用一种新颖的方法来代表单个单变量FOX-H函数的四个通道系数乘积的PDF和CDF。我们使用派生的PDF使用多变量FOX-H函数对RIS辅助系统的端到端SNR进行精确的统计分析。
Recent research provides an approximation on the performance for reconfigurable intelligent surface (RIS) assisted systems over generalized fading channels with phase noise resulting from imperfect phase compensation at the RIS. In this paper, we developed exact analysis and upper bounds on the performance of RIS-assisted vehicular communication system considering phase noise with mobility over asymmetric fading channels by coherently combining received signals reflected by RIS elements and direct transmissions from the source terminal. We employ a novel approach to represent the PDF and CDF of the product of four channel coefficients in terms of a single univariate Fox-H function. We use the derived PDF to develop an exact statistical analysis of the end-to-end SNR for the RIS-assisted system using multi-variate Fox-H function.
