Abstract

In this study, we introduce Q-MOHO (Q-Machine
Learning Guided Multi-Objective Hybrid Optimization) for power
allocation in MIMO-NOMA communication systems aided by RIS.
To optimize throughput, improve equalization, and reduce power
variation, the algorithm adjusts power distribution among three
users facilitated by 64 RIS components. Dynamically adjusting
with SNR, the optimal power distribution spans from 0.2 at
elevated SNR levels to 0.8 at reduced SNRs. The Q-MOHO
performance of 5.40 bps/Hz at an SNR of 25 dB is substantial when
contrasted with equal power allocation (EPA) and difference of
convex optimization (DCO). These results confirm that, in realworld
wireless conditions, the Q-MOHO algorithm can effectively
acquire optimal strategies and significantly enhance system
performance.
