Joint Power-control and Antenna Selection in User-Centric Cell-Free Systems with Mixed Resolution ADC
In this paper, we propose a scheme for the joint optimization of the user transmit power and the antenna selection at the access points (AP)s of a user-centric cell-free massive multiple-input-multiple-output (UC CF-mMIMO) system. We derive an approximate expression for the achievable uplink rate of...

| description | In this paper, we propose a scheme for the joint optimization of the user
transmit power and the antenna selection at the access points (AP)s of a
user-centric cell-free massive multiple-input-multiple-output (UC CF-mMIMO)
system. We derive an approximate expression for the achievable uplink rate of
the users in a UC CF-mMIMO system in the presence of a mixed analog-to-digital
converter (ADC) resolution profile at the APs. Using the derived approximation,
we propose to maximize the uplink sum rate of UC CF-mMIMO systems subject to
energy constraints at the APs. An alternating-optimization solution is proposed
using binary particle swarm optimization (BPSO) and successive convex
approximation (SCA). We also study the impact of various system parameters on
the performance of the system. |
