Abstract
A number of space-time codes have been re- cently proposed for the quasi-static, flat-fading, multipl e- antenna wireless channel with coherent receiver. In this paper we will focus on design of space-time codes that are linear in the scalar input symbols. We provide design cri- teria that take into account both the error probability and the channel capacity. We consider the error probability vi- a the union bound instead of the conventional pairwise er- ror probability and provide conditions on unitary codes to minimize the union bound. Then we provide conditions on linear codes that maximize channel capacity, i.e. capacity- efficient codes. Finally we provide design rules that optimi ze the error performance of capacity-efficient linear codes, a nd demonstrate performance improvements by means of simu- lations.Keywords
