In a code division multiple access wireless communication environment, multiuesr detection (MUD) is an important Interference cancellation technique. Recently, iterative multiuser joint decoding receivers for the system is well-researched. The receivers consist of soft-input softoutput (SISO) multiuser detector and a bank of single-user SISO channel decoders. At each iteration, extrinsic information are computed in detection and decoding stages and are then used as a priori information in the next iteration such as in Turbo decoding. The basic difficulty with the receiver is the complexity of the MUD stages. Most recently, sum-product algorithm based low-complexity SISO multiuser detector have been developed. In this paper, we develop low-complexity iterative multiuser joint decoding receivers based on these sum-product algorithm based multiuser detectors. |
