Bit Error Rate (BER) Performance of Various Digital Modulation Schemes in Three User NOMA Using SIC Under Rayleigh Fading Channel

This paper analyzes the bit error rate (BER) execution of downlink non-symmetrical various access networks for binary phase shift keying adjustment and quadrature phase shift keying regulation. BER is determined for every client under added substance white Gaussian noise and Rayleigh fading diverts in amazing successive interference cancellation (SIC) case. Then, in SIC case, the asymptotic BER articulation in a high signal to noise ratio (SNR) district in proportionate with sent power is acquired.. Then, at that point, a plausible scope of force portion coefficients is observed to such an extent that a decent BER execution can be given for every client regard to QPSK and BPSK. It has been tried for close to client and Far client BER execution regarding sent power. At last, through Recreations it are approved to utilize MATLAB insightful outcomes.
