摘要 纹状代数空时码(Threaded Algebraic Space Time code，TAST)具有在不牺牲码率的条件下获得全部分集增益的良好性能，适合于高速率传输。该文分析了全速率全分集TAST码的迫零(Zero-Forcing，ZF)检测性能，并与贝尔实验室垂直分层空时码(VBLAST)的检测性能进行比较。分析和仿真结果都表明：TAST码的ZF检测性能优于VBLAST，但其迫零排序逐次干扰抵消(ZF-Ordered Successive Interference Cancellation，ZFOSIC)检测的性能却差于VBLAST。
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.
