摘要: This paper deals with uplink Direct-Sequence Code Division Multiple Access (DS-CDMA) transmissions over mobile radio channels. A new interference cancellation scheme for multiuser detection, calledSIC/RAKE, is presented. It based on a modified multistage Successive Interference Cancellation (sic) structure that enables efficient detection in multipath propagation environments, thanks to single userRAKE receiver incorporated each unit of thesic structure. Furthermore, version structure, calledSIC/MMSE, ensures convergence theMMSE detector rather than the decorrelating has been suggested. The theSIC/RAKE andSIC/MMSE methods proved. Simulation results Universal Mobile Telecommunication System (UMTS) have carried out flat fading Rayleigh channels, showing proposed resistant near-far effect and low performance loss obtained compared single-user bound.
