METHOD AND APPARATUS FOR GENERATING EQUALISER COEFFICIENTS IN AN OFDM SYSTEM

摘要

A channel estimator (70), configured for supplying equalization coefficients (Wi) to a frequency equalizer (68), is configured for determining equalizer coefficients for a received wireless signal based on a minimum equalization error-based estimation. The channel estimator is configured for identifying first and second long preambles (100a, 100b) from the received wireless signal, determining an equalization coefficient for a selected frequency based on a minimized cost function for the first and second long preambles relative to a prescribed preamble value (102) for the selected frequency, and supplying the equalization coefficient for the selected frequency to a frequency equalizer for equalization of the received wireless signal.
