Cumulant-based adaptive multichannel filtering for wirelesscommunication systems with multipath RF propagation using antenna arrays

摘要

A method based on high-order statistics is proposed to mitigatenthe performance degradation caused by multipath RF propagation in anmobile radio communication system using a linear antenna array at thenbase-station receiver. It is shown that an overdetermined system ofnlinear equations (involving only cumulants of the received basebandndigitized signal) can be obtained to perform noniterative deconvolution.nAn efficient adaptive algorithm based on square-root decomposition isnproposed to avoid numerical problems when real-time tracking of movingntransmitters is needed
