Abstract

In this chapter, the authors address the specific problem of spectrum sharing between a multiple-input multiple-output (MIMO) ship-borne defense radar system and a commercial MIMO cellular network consisting of clusters of cooperative base stations (BS), commonly known as Coordinated Multi-Point (CoMP) system. The CoMP system coordinates simultaneous transmissions from multiple BSs to User Equipment (UE) in the downlink and perform joint decoding of UE signals at multiple BSs in the uplink. Thus, the CoMP system utilizes coordination among BSs to effectively turn otherwise harmful inter-cell interference (ICI) into useful signals. This results in improved coverage, throughput, and efficiency for overall cellular system as well as for the cell-edge users. Due to these advantages of the CoMP system over traditional cellular system, 3GPP LTE-Advanced Release 11 and beyond consider CoMP as an enabling technology for 4G mobile systems [1].
