Selecting of a pre-filter in a receiver of a communication system

摘要

Embodiments provide a receiver comprising an input coupled to a communication channel for receiving an input signal from the communication channel, a first processing filter coupled to the input, and a first level estimation module coupled to the first processing filter to estimate a first level of the input signal based upon the first processing filter. The receiver further comprises a second processing filter coupled to the input, a second level estimation module coupled to the second processing filter to estimate a second level of the input signal based upon the second processing filter, and a control module coupled to (i) the first level estimation module and (ii) the second level estimation module, wherein the control module includes logic configured to select an analog pre-filter for the input signal based upon (i) the first level of the input signal and (ii) the second level of the input sign.
