A turbo decoder included in a multi-user detector: a solution to be retained
Résumé
This paper deals with the presentation of different multi-user detectors in the UMTS context. The challenge is always to optimize the compromise between performance and complexity. Compared with the solution commonly used today, the rake detector, successive interference cancellation (SIC) detector has better performance despite its higher complexity. Our innovative solution proposes joining detector and channel turbo decoder to get a significant gain in terms of performance. Furthermore, when detection and decoding are imlemented in a single function, complexity does not increase much.
