Abstract:
For use with a wireless communication system, wherein a transmission from a desired user, and from one or more potential interferers may impinge upon a base station receiver along generally common directions passing through a common lobe of a radiation pattern of an antenna of said base station, a method of separating signals received from said desired user from an interferer comprising the steps of:(a) receiving signals from said desired user and said interferer via each of at least two antenna elements having respectively different polarizations; and (b) performing linear signal processing of signals received by said at least two diverse polarization antenna elements using information, including training sequence signals, contained in signals received from said desired user and from said interferer, and comprising estimating signals received from said desired user and from said interferer by weighting and selectively combining said received signals using polarization coefficients derived from estimated channel fading coefficients.
