Abstract: Iterative multiuser receiver for joint multiuser detection and channel decoding improves the receiver’sperformance by passing soft information between multiuser detection and channel decoding. In this paper, an iterativemultiuser receiver based on decorrelating decision-feedback detection is proposed, which is effective to implementmultiuser detection, channel decoding and parameter estimation. The data decoding and the parameter estimation arereinforced each other. The bit error rate decreases along with the increase of the iteration, and the parameter estimationapproaches the optimum at the same time.
