Method and apparatus for joint equalization and noise shaping in a software defined radio

An apparatus comprising:

• an antenna for receiving a first RF signal and a second RF signal;
• a memory for storing a filter parameter;
• a delta signal modulator for filtering the first RF signal and the second RF signal in response to the filter parameter;
• and
• a processor for tuning the delta sigma modulator in response to the first RF signal, for determining a filter parameter in response to the tuning the delta signal modulator in response to the first RF signal, and for configuring the delta signal modulator in response to the filter parameter to process the second RF signal.

A method for equalizing an RF receiver comprising:

• receiving a pilot signal having a known frequency response;
• configuring a delta sigma modulator in order to receive the pilot signal;
• generating a filter parameter in response to the configuring of the delta sigma modulator to receive the pilot signal;
• receiving an RF signal;
• determining an RF signal characteristic;
• configuring the delta sigma modulator using the filter parameter in response to the RF signal characteristic;
• and
• processing the RF signal.
