Abstract

An algorithm for optimal user grouping in wireless communication systems using PD-NOMA (Power Domain Non-Orthogonal Multiple Access) technology is proposed. The algorithm aims to minimize inter-group interference and improve the system›s interference resistance. The application of the proposed approach enables a base station with four transmit antennas to serve up to eight users, which significantly exceeds the capabilities of traditional systems employing MIMO (Multiple-Input-Multiple-Output) technology. Compared to existing user grouping algorithms, the new algorithm provides an interference robustness gain of up to 2 dB.
