Abstract

The sliding window decorrelating algorithm (SLWA) for asynchronous multi-user DS-CDMA (direct sequence code division multiple access) systems has previously been proposed. In mobile radio networks, the feasibility of overcoming the near-far problem using power control strategies is questionable at practical vehicle speeds. An alternative to rapid power control is proposed which incorporates both the RAKE diversity reception concept and the SLWA. Decorrelation is thus achieved between individual users and their significant multi-paths. A mathematical model is presented for the receiver in conjunction with simulation and numerical results which show capacity enhancements over the conventional linear correlation receiver (CLCR) and lead to ideas on a positioning strategy for decorrelating solutions in DS-CDMA mobile radio.
