摘　　要：Iterative multiuser receiver for joint multiuser detection and channel decoding improves the receiver' s performance by passing soft information between multiuser detection and channel decoding. In this paper, an iterative multiuser receiver based on decorrelating decision-feedback detection is proposed, which is effective to implement multiuser detection, channel decoding and parameter estimation. The data decoding and the parameter estimation are reinforced each other. The bit error rate decreases along with the increase of the iteration, and the parameter estimation approaches the optimum at the same time.Iterative multiuser receiver for joint multiuser detection and channel decoding improves the receiver' s performance by passing soft information between multiuser detection and channel decoding.
