Abstract

A novel strategy based on Capon method is proposed for multiple signals extraction with an antenna array in TDMA/FDMA mobile cellular systems. In this method, called SF-Capon. each Intercell Cochannel (lC) user is alternatively asked to decrease its transmitted power for a few bits. This enables the estimation of a so-called Signal-Free (SF) correlation matrix, which is then used in connection with Capon method to compute an improved beamforming weight vector, with reduced sensitivity to DOA error and angular spread. The superiority of the proposed SF-Capon strategy over standard Capon and data independent least-squares beamformingis demonstrated via simulation in a fast Rayleigh fading channel.
