Adaptively Optimizing the Algorithms for Adaptive Antenna Arrays for Randomly Time-Varying Mobile Communications Systems

Abstract : Adaptive antenna arrays are widely used and have great promise to reduce the effects of interference and to increase capacity in mobile communications systems. Consider a single cell system with an (receiving) antenna array at the base station. The usual algorithms for obtaining the antenna weights for the adaptive array depend on parameters that are held fixed no matter what the operating situation, and the performance can strongly depend on the values of these parameters.
