An Adaptive Space-Time Multiuser Detection Algorithm for CDMA Systems

摘要：

Based on the minimum mean squared error (MMSE) between the data stream and the linear combiner output, a new multiuser detection (MUD) algorithm that combines space–time (ST) processing and antenna diversity on direct-sequence CDMA signals is proposed. The new ST-MUD algorithm does not require explicit estimation of channel and signaling information, as such it avoids any channel estimation error and provides robust and accurate results. An adaptive implementation of the new ST-MUD algorithm using training sequences is given and simulated. The new ST-MUD algorithm provides a performance better than that of existing algorithms and is especially suitable for CDMA systems.
