统一统计在通信系统性能分析中具有重要的应用价值。在这种情况下，福克斯的H函数已被证明非常适合不同的场景。另一个关键要求是具有较低的计算复杂性，这对于一般模型来说通常很难实现。基于这一动机，在本文中，我们给出了中断概率(OP)和平均符号差错概率(SEP)的高功率、低复杂度的解决方案。此外，利用分集技术来减轻衰落的影响，然后基于所得到的结果对其进行分析。整个方法是由原始概率密度函数控制的，而不是近似高功率下的性能指标。通过计算机仿真(蒙特卡罗)对所有提出的数学表达式进行了比较和验证，以验证所提出的框架的准确性。
Unified statistics are valuable in the performance analysis of communication systems. In this context, Fox's H-function has been shown to be eminently suitable for diverse scenarios. Another pivotal requirement is to have a low computational complexity, which is often hard to achieve for generalized models. Given this motivation, in this article we have presented high-power, low-complexity solutions for the outage probability (OP) and the average symbol error probability (SEP). Additionally, diversity techniques are harnessed for mitigating the effect of fading, which are then analysed based on the results derived. The entire methodology is governed by the origin probability density function rather than approximating the performance metrics under high-power. All the presented mathematical expressions are compared and validated through computer simulations (Monte-Carlo) to verify the accuracy of the proposed framework.
