Abstract: A channel estimator, configured for supplying equalization coefficients to a frequency equalizer, 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 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 for the selected frequency, and supplying the equalization coefficient for the selected frequency to a frequency equalizer for equalization of the received wireless signal.
