Abstract

Interference reduction is achieved within a communication device using a low complexity antenna array. In at least one embodiment, phase and magnitude values associated with an antenna element within a low complexity array are dynamically adjusted during device operation in a manner that enhances a predetermined quality criterion (e.g., SINR).

Description

RELATED APPLICATIONS [0001] This application is a continuation of U.S. application Ser. No. 09 / 976,200 filed on Oct. 11, 2001 which is incorporated herein by reference.FIELD OF THE INVENTION [0002] The invention relates generally to communication systems and, more particularly, to interference reduction techniques for use therein. BACKGROUND OF THE INVENTION [0003] In a cellular communication system, a plurality of wireless base stations are typically used to provide communication services to mobile users within the system. Each base station will often service multiple users within a coverage region or cell associated with the base station. To allow multiple users to share a base station, a multiple access scheme is typically employed. One multiple access technique that is becoming increasingly popular is code division multiple access (CDMA). In a CDMA-based system, a plurality of substantially orthogonal codes (usually taking the form of pseudo-random noise sequences) are used to s...
