Patent ID: 6993311

Claim:
A radio receiver, comprising: a radio frequency unit for receiving a plurality of radio signals and providing a selected radio signal; an intermediate frequency unit, coupled to the radio frequency unit, for providing a digitized signal; a filter for filtering a portion of the digitzed signal and providing a filtered digitized signal; an equalizer comprising a tap update circuit having an infinite impulse response (IIR) filter and an error generator for providing error messages to the IIR filter, where a previous error message of the error messages is weighted up by a value (m) and a current error message of the error messages is weighted up by a value 1−m, the current error messages being summed with the previous error message to produce an averaged-over-time error message for updating tap values of the tap update circuit, the equalizer for selectively filtering portions of the filtered digitized signal and providing a interference-reduced digitized signal; and a demodulator/processor for demodulating the interference-reduced digitized signal and providing an audio signal derived from the interference reduced digitized signal.
