1. A receiver for use in a digital data transmission system where the data that is transmitted through a medium is presented in frames, and each of the frames includes a guard band of a given length, said receiver including a time-domain equalizer followed by demodulation and decoding circuitry, and an initialization processor, for computing operating parameters of the equalizer, the improvement comprising: said initialization processor computing, for computing an orthogonal eigenvector e min corresponding to a minimum eigen value of (√{square root over (B)}) −1 A(√{square root over (B)} T ) −1 , where 
 B=H win T H win 
 A=H wall T H wall H win is a matrix of transmission coefficients affecting signals transmitted at times d through d+CP, H wall is a matrix of effective transmission coefficients affecting signals transmitted at times 0 through N+t−2, d is an integer N is channel impulse response, t is number of equalizer filter taps, and CP is length of a cyclic prefix, to obtain filter coefficients vector w, corresponding to (√{square root over (B)} T ) −1 e min .
