Patent ID: 7321550

Claim:
An equalization method suitable for use in a receiver in an orthogonal frequency division multiplexing (OFDM) system utilizing a plurality of sub-carriers, wherein the receiver includes an outer receiver for decoding, the method comprising: receiving an input signal including at least one preamble symbol containing a training sequence and a plurality of informative OFDM symbols each containing a serial stream of samples; performing compensations for each of the informative OFDM symbols, including converting the serial stream of samples into parallel samples, performing a fast Fourier transform (FFT) of the parallel samples to obtain, in the frequency spectrum, a plurality of data symbols, wherein each data symbol corresponds to a sub-carrier, compensating the data symbols for at least one first phase distortion, compensating the data symbols for at least one second phase distortion; and providing at least one amplitude distortion factor to the outer receiver.
