For its ability to deliver a larger spectral efficiency, NOMA is recognized as a vital enabling technology for 5G networks. • In contrast to conventional Frequency Division Multiplexing, the spectral overlapping among sub-carriers are allowed in OFDM since orthogonality will ensure the sub-carrier separation at the receiver, providing better spectral efficiency and the use of steep bandpass filter was eliminated.

ABSTRACT-The modern wireless system consists of complex base stations with a high power transmitter in which channel characteristics should be. Checkout period is 16 weeks, with no renewals. The results for 2×2 MIMO with Maximum Likelihood (ML) equalization helped us to achieve a performance closely matching the 1 transmit 2 receive antenna Maximal Ratio Combining (MRC) case.
