The combination schemes of Space-Time Block Code (STBC) and Code Division Multiple Access (CDMA) have attracted much attention. This paper focuses on the combination schemes of STBC and Digital Matched Filter (DMF), Zero Forcing (ZF) and investigates the effect of channel estimation deviation on these schemes’ performance. The detailed theoretical analyses and simulation results are provided. The results show that for the assumed ideal receiver data without the effect of Gaussian noise, the channel estimation deviation worsens the performance bound and for the real receiver data, the deviation degrades the link performance by at least 1.5?dB no matter of DMF and ZF algorithms.
