when power increases in a Rayleigh fading channel, the bit error rate drops, greater power is
distributed to far users while low power is distributed to nearby users, ensuring user fairness.
Similar findings are obtained with Nakagami fading, although the BER performance is
superior to that of Rayleigh fading. The Nakagami channel performs better than the Rayleigh
channel in terms of Bit Error Rate. A rise in BER might be reduced by the employment of
several coding techniques or differentiation strategies.
