Joint Spatial Coding and Spatial Multiplexing: Optimal and Suboptimal Criteria

Abstract

In this contribution, spatial coding diversity is combined with spatial multiplexing to get higher joint gains on ensuring both low error rate and high spectrum efficiency. A general mathematical model of joint spatial coding and multiplexing (JSCM) is proposed and analyzed. Optimal criteria and a suboptimal iterative algorithm on the design of JSCM are studied. Performance of JSCM is proved by simulations from various aspects.
