An apparatus for mitigating distortion effects and enhancing signal usability determinations in a receiver, the apparatus comprising: a signal receiver (202) that receives a stream of information symbols to produce a symbol stream; a distortion characteristics determiner (204), wherein the distortion characteristics determiner determines distortion characteristics for a distortion component of each information symbol of the symbol stream; a desired component determiner determines a desired component for each information symbol of the symbol stream; an undesired component determiner (206), operably coupled to the desired component determiner and the signal receiver, wherein the undesired component determines an undesired component for each information symbol of the symbol stream based on the desired component and the symbol stream; interference component determiner (209), operably coupled to the undesired component determiner and the distortion characteristics determiner, wherein the interference component determiner determines an interference component for each information symbol of the symbol stream based on the desired component, the distortion characteristics, and the undesired component; a magnitude scaler (208), operably coupled to the interference component determiner, the distortion characteristics determiner, and the undesired component determiner, wherein the magnitude scaler scales a magnitude of the undesired component by a first predetermined value when the magnitude of the undesired component is less than at least one magnitude value and scales the magnitude of the undesired component by a second predetermined value when the magnitude of the undesired component is greater than the at least one magnitude value; and a filter (207), operably coupled to the distortion characteristics determiner and the undesired component determiner, wherein the filter attenuates the distortion component from the undesired component. |
