In this research outage probability is analysed for a proposed matrix based method using selection combining diversity under shadowed attenuation in a typical macrocell environment. The conventional Lognormal shadowing model approximates the gamma probability density function which is used in proposed matrix based method. The closed form expressions are developed for evaluating the probability of outage in multipath fading environment with the help of shadow matrix, shape, and scale factors. The graphical results using proposed method are validated by comparing them with the Lognormal method. The presented results have been investigated by varying threshold in terms of shadow based attenuation. The results obtained using proposed method is compared with the Lognormal model where shadowing spread is varied. It is clear from the plots that the outage probability using proposed model shows better results the outage probability as compared to Lognormal shadowed model.

在这项研究中，在典型的宏小区环境中，在阴影衰减下使用选择组合分集对基于矩阵的方法提出的中断概率进行了分析。传统的对数正态阴影模型近似于在基于矩阵的方法中使用的伽马概率密度函数。开发了封闭形式的表达式，以借助阴影矩阵，形状和比例因子来评估多径衰落环境中中断的可能性。通过将其与对数正态方法进行比较，验证了所提出方法的图形结果。通过根据基于阴影的衰减改变阈值来研究呈现的结果。使用提议的方法获得的结果与阴影扩散变化的对数正态模型进行比较。
