RAKE DECORRELATING RECEIVER FOR DS-CDMA MOBILE RADIO NETWORKS

The sliding window decorrelating algorithm (SLWA) for asynchronous multiuser (MU) DS-CDMA systems was proposed and described by Wijayasuriya et al. The near-far (NF) resistance of the algorithm was established, and its performance evaluated in single path fading channels. In the Letter, a RAKE-SLWA receiver architecture is proposed for an urban mobile radio environment, which alleviates the requirement for complex power control strategies and offers large capacity improvements over the conventional receiver. A positioning strategy is also identified for decorrelating solutions in DS-CDMA mobile radio.
