Capacity improvement with base-station antenna arrays in cellular CDMA

Abstract

The use of an antenna array at a base-station for cellular CDMA is studied. The authors present a performance analysis for a multicell CDMA network with an antenna array at the base-station for use in both base-station to mobile (downlink) and mobile to base-station (uplink) links. They model the effects of path loss, Rayleigh fading, log-normal shadowing, multiple access interference, and thermal noise, and show that by using an antenna array at the base-station, both in receive and transmit, one can increase system capacity several fold. Simulation results are presented to support the claims.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
