Abstract In the current work we have used the presence of a-μ for maximal ratio combining. Besides, we have assessed the mean level crossing rate of output signal of wireless communication system. The level crossing system offers the advantage of the mean fade duration of the wireless system. Besides we have studied the dual and triple MRC receivers. We have given... In the current work we have used the presence of a-μ for maximal ratio combining. Besides, we have assessed the mean level crossing rate of output signal of wireless communication system. The level crossing system offers the advantage of the mean fade duration of the wireless system. Besides we have studied the dual and triple MRC receivers. We have given the testing results to document the influence of fading parameters on the functioning of systems. Read More Read Less
