Patent ID: 7474719

Claim:
A method for de-sensing a composite signal having a plurality of frequency-based channels, the method comprising: (a) channelizing the composite signal to generate a plurality of channel signals, each channel signal corresponding to a different carrier frequency in the composite signal; (b) independently adding a specified level of noise to each channel signal to generate a de-sensed channel signal, wherein the specified levels of noise for at least two channel signals are different; and (c) processing each de-sensed channel signal to enable characterization of effect of the added noise, wherein; step (a) further comprises performing automatic gain control (AGC) processing; step (b) comprises, for each channel signal: (1) processing the channel signal to undo the AGC processing to generate a scaled channel signal; (2) adding the specified level of noise to the scaled channel signal to generate a noise-scaled channel signal; and (3) processing the noise-scaled channel signal to redo the AGC processing to generate the de-sensed channel signal.
