Abstract
A receiver is disclosed that is capable of correcting for harmonic distortion injected into received analog signals. The receiver splits the analog signal in the analog front-end and modifies the split analog signals with a difference signal. After amplification and/or sampling, the modified analog signals are recombined in a main data pathway and are kept separate in a secondary pathway. Utilizing the difference signal, a feedback loop that includes distorters and an LMS filter detects the distortion coefficient of the harmonic distortion. A distorter in the main data pathway utilizes the detected distortion coefficient to correct the harmonic distortion in the analog signal.
