Abstract
A method for calculating filter coefficients for an equalizer in a communication receiver, the method including the steps of calculating () channel response matrices G and H from channel estimation inputs; performing () a Cholesky decomposition of the channel response matrix G into a lower triangular matrix L and an upper triangular matrix U; performing () forward substitution on the lower triangular matrix L to calculate a column vector d; performing () backward substitution on the column vector d and the Hermitian transpose Lof the lower triangular matrix L to calculate a middle column cof the inverse Gof the channel response matrix G; and calculating () the filter coefficients from the middle column cof the inverse channel response matrix Gand the Hermitian transpose Hof the response matrix H.
