摘要：
Space-time block coding (STBC) is a promising candidate for the next generation cellular communications standard, especially in the downlink system. In the downlink WCDMA system, multiple access interference (MAI), which impairs performance of the receiver, can be eliminated by channel chip level equalization. In this paper, different schemes for STBC over frequency selective fading channels in downlink WCDMA systems are introduced. Simulation results show that the combination of channel chip equalization and STBC (symbol level as well as chip level) provides better performance.
