Performance of Cyclic Prefix Assisted Single Carrier CDMA Uplink System with MIMO Multiplexing Zhaoxi Fang 1

In this paper, we describe a novel type of cyclic prefix assisted single carrier CDMA system with Frequency Domain Equalization (FDE) and MIMO Multiplexing. The proposed method is referred to as MIMO SC/FDE CDMA. Multipath Interference can be mitigated by inserting cyclic prefix at the transmitter. Furthermore, we use different scrambling codes to separate different transmit antennas. At the receiver, Frequency Domain Equalization was employed with an iterative soft interference cancellation method. Simulation results show that the proposed MIMO SC/FDE CDMA system can achieve high performance while still keeping low complexity.
