Layered space-time coding: performance analysis and design criteria

A layered space-time architecture has been proposed to realize the tremendous increase in capacity which is offered by rich scattering wireless channels in comparison with a single transmit and single receive antenna case. We analyze the performance of horizontally (HLST) and diagonally (DLST) layered space-time architectures on slow and fast Rayleigh fading channels. Based on the analysis, we derive the code design criteria for the constituent codes for each architecture.
