Abstract
Official abstract text for this publication.
A wideband phase detector configured to receive an intermediate frequency (IF) signal having a plurality of information signals at predetermined carrier frequencies and to generate a carrier indication signal used to control one or more attenuators to equalize the signal levels of the information signals thereby enabling a multichannel receiver to process the two information signals in a parallel fashion using a common analog front-end and analog to digital conversion circuit. The circuit may include an attenuation controller configured to provide control signals to the one or more attenuators to attenuate one or more corresponding information signals based on an average of the carrier indication signal.
First claim
Opening claim text (preview).
What is claimed: 1. A method comprising: receiving an intermediate frequency (IF) signal having a plurality of information signals at predetermined carrier frequencies; generating a carrier indication signal by processing the IF signal with a wideband phase detector; attenuating at least one of the information signals based on an average of the carrier indication signal; and iteratively determining the average of the carrier indication signal and attenuating the at least one…
