|Abstract:||In this paper we introduce a modified interference cancellation scheme for multiuser detection in CDMA. This detector combines the successive and parallel interference cancellation concepts, and hence is called a hybrid interference canceller (HIC). In the HIC, the active users are split into a number of groups. Within each group, parallel detection is performed. Between the groups, serial cancellation is carried out. The performance is evaluated over both single-path and multipath channels and it is shown through simulation that the HIC detector has performance close to the successive interference canceller, but with much less detection delay. The detector also overcomes the `ping-pong' behaviour of the conventional parallel interference canceller at the cost of additional detection delay.|
