Downlink DSTBC-WCDMA in a fast time-dispersive channel
In this paper, the Differential Space-Time Block Code (DSTBC) modulation is applied to the downlink transmission of the WCDMA system to enhance system performance in fast-varying time-dispersive channels. The effect of scrambling operation is also considered to improve correlation between users'...
