Abstract :
A structure for performing iterative multiuser detection for serially concatenated convolutionally coded (SCCC) CDMA is proposed. Extrinsic information is produced for the multiuser detector and exchanged between the SCCC component decoders. It is shown that for heavily loaded SCCC asynchronous CDMA, near single-user performance can be achieved
