Abstract
The invention discloses an interference cancellation circuit for a receiver to process an input signal which is carried on a first carrier frequency and includes a transmitted signal and at least one interference signals. The interference cancellation circuit comprises a down-converter for converting the input signal to dc location to generate a down-converted signal; a first path circuit for processing the down-converted signal to generate a first processed signal which includes the transmitted signal and the interference signals; a second path circuit for processing the down-converted signal to generate a second processed signal which includes only the interference signals; and a combiner for generating an output signal by combining the first processed signal and the second processed signal.
