Abstract Threaded Algebraic Space Time (TAST) code achieves the full diversity gain without the loss of code rate, and fits the high-rate transmission. In this paper the Zero-Forcing (ZF) detection’s performance of the full-rate full-diversity TAST code is analyzed and compared with VBLAST. Theoretical analysis and simulation both show that the TAST’s ZF detection performance is better than the VBLAST’s, but their ZF-ordered successive interference cancellation (ZFOSIC) performance is alternated.
