A real-time approach to array control based on a learned genetic algorithm

In the framework, of wireless communications, it is mandatory to guarantee the reliability of the receiver by assuring good quality the end-user, in order to successfully decode transmitted signals. To this end, a method for the design of adaptive antenna arrays is described in this paper. The proposed procedure, based on a customized genetic algorithm, allows real-time control of the receiver's performance by acting on the discretized phase coefficients of the array elements. As a result, at the receiver, multiple and alternating interferences are considerably reduced with respect to the desired signal. In order to validate the proposed strategy, selected numerical results, concerning various environment conditions, are presented and deeply discussed. (C) 2003 Wiley Periodicals, Inc.
