Patent ID: 7613260

Claim:
A receiver, comprising: an input circuit, which is coupled to at least one antenna so as to receive, process and digitize first and second signals, thus generating first and second streams of input samples; and an interference cancellation circuit, comprising: first and second adaptive filters, which are respectively coupled to filter the first and second streams of input samples using respective first and second coefficients to generate respective first and second filter outputs; a phase rotator, which is adapted to apply a variable phase shift between the first and second signals, the phase rotator having at least one configuration parameter; and a control module, which is operative to compute the variable phase shift and to provide the variable phase shift to the phase rotator so as to compensate for a phase deviation between the first and second signals, to estimate interference in the first signal due to the second signal, and to set the at least one configuration parameter of the phase rotator responsively to the estimated interference.
