摘要

本文研究了新提出的Beaulieu-Xie衰落信道在不同传输策略下的容量。这种衰落分布用于模拟具有多个视距(LOS)分量的无线信道，其中含有由于多个散射体而产生的一些间接射线。以半封闭形式导出了最优功率和速率自适应(OPRA)、最优速率自适应(ORA)、固定速率信道反转(CIFR)和截断固定速率信道反转(TIFR)条件下的信道容量表达式。通过文献中已经充分记录的特殊情况和通过蒙特卡罗模拟，观察到完全一致，从而证实了导出表达式的有效性，验证了导出表达式。

Capacity of the Beaulieu-Xie Fading Channel under Adaptive Transmission Strategies

In this paper, we study the capacity of the recently proposed Beaulieu-Xie fading channel under different trans-mission strategies. This fading distribution is used to model wireless channels characterized by multiple line-of-sight (LOS) components with some indirect rays due to multiple scatterers. Novel expressions for the channel capacity under optimum power and rate adaptation (OPRA), optimum rate adaption (ORA), channel inversion with fixed rate (CIFR) and truncated channel inversion with fixed rate (TIFR) are derived in semi-closed form. The derived expressions are verified through special cases that are already well-documented in the literature and through Monte-Carlo simulations where perfect agreement is observed thus confirming the validity of the derived expressions.
