Abstract

The authors previously presented a new space-time architecture combining generalized layered transmission, advanced iterative multi-user detection techniques, and space-time code design that provides superior performance compared to the layered architectures proposed by Foschini (1996) and Tarokh et al. (see IEEE Trans. on Information Theory, vol.IT-44, p.744-65, 1998). We discuss the design of algebraic space-time codes for layered and non-layered architectures. We present new constructions for the quasi-static and block fading channels that extend to the diagonal transmission architecture proposed for differentially coherent space-time coding
