摘要
We present methods for the multi-user interference cancelation in a Code Division Multiple Access (CDMA) system where Turbo Codes are utilized for Forward Error Correction (FEC). In the proposed methods, the individual users are decoded separately with the operation of iterative interference cancelation being mixed with the iterative decoding of Turbo Codes. This results ill a modest increase in the overall complexity as compared to a conventional single user receiver utilizing Turbo Codes. Numerical results are presented showing that ill the cases of practical interest for CDMA applications, the multiple access interference call be essentially removed at a reasonable level of complexity. These iterative decoders achieve a similar to better performance with a substantial reduction in the complexity as compared to similar previously known research works.
