Study of Non-Orthogonal Multiple Access (NOMA) technology performance over AWGN channel and Rayleigh fading channel
Abstract
The design of the next generation of wireless networks depends on introducing significant improvements, and uses highly spectral efficiency multiple access technologies due to the limited bandwidth resources available. As maintaining connectivity forms a challenge to spectral efficiency, and there is no single basic technology that can fit all 5G requirements, NOMA have become an option available for 5G and beyond because it is a promising technology that would satisfy the low latency requirements, huge number of connections and high data rate for this generation's networks.
This research examined this technique and compared it with traditional OMA techniques, explaining the principle of its functioning, and then examining mobile NOMA communication system performance over AWGN channel by evaluating BER performance versus SNR in addition to Rayleigh fading channel through studying the achievable capacity versus transmit power, as well as BER performance versus transmit power.
