Aazhang, "Computationally Efficient Iterative Multiuser Detection and Decoding," 1998.https://hdl.handle.net/1911/19822Conference paperWe describe an iterative detection and decoding scheme for the uplink in a convolutionally coded direct sequence code division multiple access (DS-CDMA) system. We consider maximum-a-posteriori (MAP) decoding and reduce the complexity through an iterative interference cancelation scheme combined with a suboptimal channel decoding algorithm. The MAP priors are updated at every iteration step. We investigate the performance of this low complexity scheme and observe that it is close to optimal.engdirect sequence code division multiple access (DS-CDMA)iterative multiuser detectiondecodingmaximum-a-posteriori (MAP)Conference paperdirect sequence code division multiple access (DS-CDMA)iterative multiuser detectiondecodingmaximum-a-posteriori (MAP)
