Abstract: 

Two main problems in CDMA cellular systems are multiple access interference (MAI) and multipath fading. To alleviate these problems, two usually used methods are multiuser detection and space-time coding. In this paper, we study multi-user detection of CDMA signals in multiple transmit receive antenna systems. We propose some structures that use combinations of linear and non-linear multi-user detection techniques with space-time block coding method. Then, we compare the performance of the proposed receiver structures by computer simulations. We also compute the complexity of the proposed space-time multi-user detectors and compare them.
