Patent ID: 7706437

Claim:
A compensation system comprising: a digital demodulator circuit configured to generate a corrected complex signal by correcting at least one error introduced into a complex signal during wireless transmission, the digital demodulator circuit comprising: an equalizer tap calculation circuit configured to cooperate with an equalizer tap tracking circuit to correct at least one of time-constant and time-varying channel effects of the complex signal; a phase tracking circuit configured to correct a residual carrier frequency offset of the complex signal; a timing tracking circuit configured to correct a sampling frequency offset of the complex signal; where the digital demodulator circuit is configured to receive the complex signal from a Fast Fourier Transform (FFT) circuit; where the digital demodulator circuit is configured to provide the corrected complex signal to a soft decision demapper; and where the equalizer tap calculation circuit is configured to generate a corrective tap signal to each subcarrier associated with the complex signal by applying an algorithm to a plurality of subcarriers comprising the complex signal.
