Patent ID: 7792213

Claim:
A method comprising: a. generating a plurality of discrete sampled IQ values based on an input signal, wherein each sampled IQ value includes an in-phase component and a quadrature component; b. comparing each sampled IQ value to a defined minimum IQ value; c. for each specific sampled IQ value that is less than the minimum IQ value, determining a specific scaling factor to be applied to the specific sampled IQ value, wherein the specific scaling factor is determined according to a relative difference between the specific sampled IQ value and the minimum IQ value; and d. applying the specific IQ scaling factor to the specific sampled IQ value, thereby generating a scaled IQ value, wherein the scaled IQ value exceeds the minimum IQ value, further wherein the specific IQ scaling factor is applied to the in-phase component and the quadrature component of the specific sampled IQ value, wherein the determined scaling factor is selected from a set of scaling factors, wherein each scaling factor in the set of scaling factors is associated with a range of distances from the minimum IQ value.
