| 摘要 |
The present invention relates to a method of parallel interference cancellation in mobile telecommunication system. The signal of partly parallel interference cancellation is obtained by multistage PIC structure processing of each user signal, wherein, in the middle stage and the last stage of PIC structure. The result of multipath despreading of any user in the previous stage of PIC structure and the result of multipath despreading of the same user in the present stage of PIC structure are combined together, thereby the combined result of multipath despreading of the same user in the present stage of PIC structure is obtained. An apparatus of parallel interference cancellation, comprises multistage PIC structure, which mainly consists of RAKE receiver, hard-decision device, reliability coefficient generator, signal regenerator, multiple access interference estimate and interference cancellation device, despreading device, stage combinator, channel estimate and multipath combination device.
