BD precoding schemes for cognitive MIMO system

Abstract

This paper focuses on pre-coding schemes for the downlink of multiple user multi-input multi-output (MU-MIMO) system in cognitive radio (CR) network. The spectrum band can be utilized by allowing a number of cognitive users to coexist with primary users (PUs) through a pre-coding scheme. The capacity problems maximize the sum rate of CUs subject to the… (More)
