Study on performance of MIMO and NOMA system

Abstract

New technologies and techniques in the field of wireless communication have been developed in response to the growing demand for high-speed and reliable wireless communication services. The sixth generation (6G) of communication networks uses multiple-input multiple-output (MIMO) and non-orthogonal multiple access (NOMA) to fulfil the high data rate need. Two cutting-edge methods that have attracted a lot of interest recently are MIMO and NOMA. In comparison to conventional single-antenna systems, MIMO, which employs multiple antennas at the transmitter and receiver, offers higher capacity and improved spectral efficiency. On the other side, NOMA can significantly boost system capacity and enhance user fairness since it uses power domain multiplexing to let multiple users share the same frequency band.This study compares MIMO with NOMA in-depth using a variety of performance criteria, including spectrum efficiency, channel prediction, and detection. The findings of this study suggest that both MIMO and NOMA have certain benefits and drawbacks, and that the decision between the two depends on the particular needs of the application situation.
