Layered Space-Time Complex Field Coding: Full-Diversity with Full-Rate, and Tradeoffs

Multi-antenna systems allow for a significant increase in the transmission rate of coherent wireless transmissions over flat Rayleigh fading channels. Various multi-antenna designs have been developed in recent years targeting either high-performance, or, high rate. In this paper, we design a layered space-time (ST) scheme equipped with linear complex field (LCF) coding, which enables full diversity with full rate, for any number of transmitand receiveantennas. Furthermore, we delineate the tradeoff between diversity and rate in the class of layered ST schemes, when sub-optimal decoding is employed. Our theoretical claims are confirmed by simulations.
