A next step (302) includes training the finite-impulse-response filter with a set of symbols of specific quadrature phase, known a priori, in the burst of data of the received waveform. For example known real only and imaginary only symbols are alternatively selected from a midamble of the data burst. A next step (304) includes operating on the received waveform with the finite-impulse-response filter to alternately linearly equalize the burst of data to provide an estimate of the desired signal.

The set of output values (306) are stored and a backward recursion portion (302) obtains the set of output values (306) and also receives the data representing the auto-covariance matrix (22), and generates filter coefficients (208) based on this information.
