Patent ID: 7474883

Claim:
A receiver in a radio communication system configured to optimize use of an available dynamic range, comprising: an automatic gain controller in an automatic gain control loop; a first measuring device coupled to the automatic gain controller and configured to measure a total received energy; a second measuring device coupled to the automatic gain controller and configured to measure an inband signal energy, wherein the automatic gain controller sets a target inband energy in accordance with the expression: ( SE ) = { IE if ⁢ ⁢ AE ≤ MAX_AE IE - ( AE - MAX_AE ) if ⁢ ⁢ AE > MAX_AE wherein AE =TE −IE is the adjacent energy and TE is the total energy, and MAX_AE is the maximum allowable level of the adjacent energy (AE),and wherein the automatic gain controller is configured to adjust the gain based on the total received energy, the inband signal energy and the target inband signal enemy, such that the inband signal enemy comes close to the target inband energy.
