Performance analysis of large‐scale MIMO system for wireless backhaul network

Abstract

In this paper, we present a performance analysis of large‐scale multi‐input multi‐output (MIMO) systems for wireless backhaul networks. We focus on fully connected N nodes in a wireless meshed and multi‐hop network topology. We also consider a large number of antennas at both the receiver and transmitter. We investigate the transmission schemes to support fully connected N nodes for half‐duplex and full‐duplex transmission, analyze the achievable ergodic sum rate among N nodes, and propose a closed‐form expression of the achievable ergodic sum rate for each scheme. Furthermore, we present numerical evaluation results and compare the resuts with closed‐form expressions.
