Bi-Objective Power Optimization of Radio Stripe Uplink Communications

The radio stripe (RS) system is a practical implementation of cell-free mMIMO, in which set multi-antenna access points (APs) serves at the same time-frequency resources user equipment (UE) network. APs are sequentially connected stripe, sharing fronthaul link to central processing unit. This work considers an uplink power optimization problem that aims enhance network spectral efficiency (SE) by considering two metrics—the max–min fairness and max–sum rate. We employ meta-heuristic based on differential evolution algorithm solve bi-objective problem. SE performances full along with single-objective multiple-objective scenarios analyzed compared for optimal sequential linear detection scheme. approach able unveil trade-offs identify solution balancing distribution resulting from rate objective functions.
