Adaptive Duplicated Filters and Interference Canceller for DS-CDMA Systems: Part II - FPGA Implementation

Many multiuser detection (MUD) methods are proposed in the literature to increase the performance of 3G cellular networks. However, it is known that the implementation complexity represents a key issue for deployment of the MUD. A VLSI implementation strategy and hardware resources evaluation of a new MUD based on the adaptive duplicated filters plus interference canceller (ADIC) method (Nougaru et al., 2007), is proposed. The maximum number of users in FPGA devices is presented with respect to WCDMA constraints. The two papers provide a low complexity MUD giving a good tradeoff performance and implementation cost.
