Abstract
An equalization method suitable for use in a receiver in an orthogonal frequency division multiplexing (OFDM) system utilizing a plurality of sub-carriers. The receiver includes an outer receiver for decoding. The equalization method includes 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, and performing compensations for each of the informative OFDM symbols. Compensation for each of the informative OFDM symbols includes converting the serial stream of samples into parallel samples, performing a fast Fourier transform (FFT) of the parallel samples to obtain a plurality of data symbols, each data symbol corresponding to a sub-carrier, compensating the data symbols for at least one first phase distortion and at least one second phase distortion, and providing at least one amplitude distortion factor to the outer receiver.
