论文摘要
本文着重于在高频毫米波（MMWave）和Terahertz（THZ）通信链路上提供一个分析框架，以量化和评估一般情况下的指向误差。为此，我们首先得出具有不同天线模式的不稳定发射器（TX）和接收器（RX）之间指向误差的概率密度函数（PDF）和累积分布函数（CDF），这些误差在YAW和螺距方向上的振动不同。还研究了TX和RX都配备均匀线性阵列天线的特殊情况。此外，使用$α-μ$分布，这是用于MMWave/Thz链接的小规模褪色的有效模型，对于所有考虑的情况，都会得出所考虑的通道的端到端PDF和CDF。最后，通过使用蒙特卡洛模拟，验证了分析表达式的准确性，并研究了系统的性能。
This paper focuses on providing an analytical framework for the quantification and evaluation of the pointing error for a general case at high-frequency millimeter wave (mmWave) and terahertz (THz) communication links. For this aim, we first derive the the probability density function (PDF) and cumulative distribution functions (CDF) of the pointing error between an unstable transmitter (Tx) and receiver (Rx), that have different antenna patterns and for which the vibrations are not similar in the Yaw and Pitch directions. The special case where the Tx and Rx are both equipped with uniform linear array antenna is also investigated. In addition, using $α-μ$ distribution, which is a valid model for small-scale fading of mmWave/THz links, the end-to-end PDF and CDF of the considered channel is derived for all the considered cases. Finally, by employing Monte-Carlo simulations, the accuracy of the analytical expressions is verified and the performance of the system is studied.
