Abstract

The use of adaptive arrays in a multi-rate multi-media CDMA network is analyzed, and simulation results are provided for a candidate two-rate system. Our proposed approach uses reference signal-based adaptation (LMS) for antenna weight control. Simulation results show adaptive arrays can significantly enhance the multi-media services that can be provided by a CDMA network. In addition, preliminary simulation results for RLS and LMS weight control algorithms are presented
