摘要: An apparatus and method reduce distortion in a processed signal. The includes first receive path, second summation unit, compensation unit. path is configured to process received analog signal into digital the with phase shift unit sum signals form identify conjugate of signal, apply weighting factor weighted subtract from distortion.
