ABSTRACT:
This invention relates to a system and method utilizing a receiver architecture with a set of at least two antennae followed by a Rake demodulator at a mobile station for interference cancellation and diversity combining. Such a structure can work well only when the channel vector of desired signal is correctly estimated. The present invention makes use of the identifying spreading codes (as in IS-95 for example) to provide an adaptive channel vector estimate, to thereby cancel cochannel interference and improve the system capacity.
