Rate-splitting multiple access for secure communications over cr miso swipt systems with non-linear eh users

HIGHLIGHTS

• What: In this paper, the goal is to design a secure scheme to jointly its consequential impact on the system model and problem formulation. To tackle this complexity, the study proposes a novel scheme called ACOR-SDR which is based on two-step solution methodology. The authors investigate the performance of particle swarm optimization (PSO) technique with SDR as a comparative approach to validate the superiority of the proposed ACOR-SDR framework. For comparison purposes, the authors investigate the nonorthogonal multiple-access (NOMA) technique, spacedivision multiple-access (SDMA) method and the Zeroforcing (ZF) as baseline schemes in . . .
