Patent ID: 7565125

Claim:
A receiver comprising: analog-to-digital circuitry for generating a digital representation, comprising a bit signal, of an amplified analog signal at an input; adjustable gain control circuitry for receiving a radio signal and outputting the amplified analog signal using a gain determined by a magnitude of the amplified analog signal, the gain being connected directly to the bit signal at an output of the analog-to-digital circuitry; digital channel filtering circuitry for filtering said digital representation; and digital processing circuitry for processing the output of said digital channel filtering circuitry, wherein the gain is adjusted by a first amount responsive to a first bit selected from a predetermined plurality of most significant bits in the bit signal, the first bit indicating that the output of the analog-to-digital circuitry has exceeded a first saturation threshold, wherein the gain is adjusted by a second amount responsive to a first set of bits selected from the predetermined plurality of most significant bits in the bit signal, the first set of bits indicating that the output of the analog-to-digital circuitry has exceeded a second saturation threshold, wherein the first amount is not equal to the second amount, and wherein the first saturation threshold is not equal to the second saturation threshold.
