Abstract

This paper presents a simple multiple-input multiple output (MIMO) hybrid system for wireless channels trying to achieve near optimal values of diversity-multiplexing tradeoff. The hybrid systems studied combine well known space time codes and full multiplexing schemes. A decoding procedure for the hybrid systems using linear combinatorial nulling and symbol cancellation is also presented. Through computer simulation upon different digital modulation constellations, the error performance and spectral efficiency of the hybrid systems are compared to the diversity-only and multiplexing-only schemes.
