Abstract
A communication system having a forward link and/or reverse link comprising: at least one base station which transmits multiple radio frequency (RF) signals; and a mobile station, the mobile station including: a receiver for receiving the RF signals; means for converting the RF signal to an intermediate frequency (IF) signal; means for sampling the IF signal to generate a digital signal, the digital signal having a data component and an interference component; means for canceling co-channel and or cross-channel interference in the digital signal by projecting the IF signal into a subspace orthogonal to a subspace of the interference component and multiplying this projection with the digital signal; and means for acquisition and tracking of the digital signal.
