Impact of co-channel interference on performance of power domain-based multiple access

摘要

Power domain-based non-orthogonal multiple access (PDMA) is one emerging technology thanks to higher system capacity, lower latency, and massive connectivity. Such PDMA is proposed to address several challenges in the fifth-generation wireless systems. In this paper, we first reveal that the non-orthogonal multiple access (NOMA) techniques have evolved from fairness assurance under impact of co-channel interference (CCI). Then, we comprehensively investigate on signal to noise ratio (SNR) to detect two separated signals, then outage performance evaluations of the two users are conduced. Monte Carlo simulations are deployed to verify exactness of outage probabilities.
