Signal fading can drastically affect the performance of terrestrial communication systems. Fading caused by multipath propagation can degrade the bit-errorrate (BER) performance of a digital communication system resulting data loss or dropped calls in a cellular system. The Nakagami-m distribution has gained widespread application in the modeling of physical fading radio channels. The primary justification of the use of Nakagami-m fading model is its good fit to empirical fading data. It is versatile and through its parameter m, we can model signal fading conditions that range from severe to moderate, to light fading or no fading. This research paper discusses the generation of Nakagami – m data and once, the Nakagami-m distribution is generated, we applied BPSK modulation technique with Equal Gain Combining [EGC] Diversity technique and Maximal Ratio Combining [MRC] technique to study its SNR (Signal – to – Noise Ratio) and BER.
