Abstract:
A baseband receiver and corresponding methods are arranged and configured to mitigate effects of direct current (DC) distortion and process an Orthogonal Frequency Division Multiplexing (OFDM) signal as provided from a direct conversion radio or receiver. The baseband receiver includes an OFDM demodulator configured to demodulate the OFDM signal, a post processor coupled to the OFDM demodulator and configured to provide symbols corresponding to the OFDM signal, and a compensator coupled to at least one of the OFDM demodulator and the post processor and configured to reduce error rates out of the baseband receiver that result from DC distortion in the direct conversion radio.
