Abstract
A system is provided with circuits and methods for dynamically reducing interference to maintain linear system operation and mitigate interference degradation to desired signal components. The system can include a binning subcircuit system configured to divide the digitized input signal into a plurality of spectral bins each having a power level. A power analysis subcircuit can be coupled to the binning subcircuit and configured to compare a collective power level of spectral bins to a threshold level that would produce nonlinear system operation. Based upon the collective power level exceeding the threshold level, outputting a gain control signal to a variable gain amplifier so that the system remains linear. This dynamic gain control can be applied to systems that receive and/or transmit signals. Residual interference components that degrade signal components can be dynamically removed by excision and the distortion introduced by the excision process can be reduced with equalization circuitry.
