Dynamic range signal to noise optimization system and method for receiver

摘要

A system and method for enhancing the dynamic range of a receiver without degrading the signal to noise ratio of an incoming signal is disclosed. In one embodiment, an enhanced dynamic range receiver for receiving an incoming signal and processing the incoming signal comprises a plurality of VGAs alternately connected in series with a plurality of equalizers to form a VGA-equalizer chain, the VGA-equalizer chain adapted to receive the incoming signal and operable to generate a first analog signal, a first PD adapted to receive the first analog signal and operable to adjust the equalizers' coefficient values, and a second PD adapted to receive a second analog signal from a selected node in the VGA-equalizer chain and operable to adjust the gain of the VGAs.
