Patent ID: 7305026

Claim:
A method of equalizing a signal, wherein the signal comprises a series of input blocks of coded data, the method comprising at least the following steps: a) shifting data in each input block of data to the left; b) complex multiplying each of the left shifted input block of data by a first set of equalizer coefficients to provide respective first adjusted output blocks of data, wherein step b) is not a full solution to ghosts; c) complex multiplying each of the input blocks of data by a second set of equalizer coefficients to provide respective second adjusted output blocks of data, wherein step c) is not a full solution to ghosts; d) shifting the data in each input block of data to the right; e) complex multiplying each of the right shifted input block of data by a third set of equalizer coefficients to provide respective third adjusted output blocks of data, wherein step e) is not a full solution to ghosts; f) adding corresponding ones of the first, second, and third adjusted output blocks of data; and, g) controlling the first, second, and third sets of equalizer coefficients so that, as a result of the addition performed according to step f), a substantially full solution to ghosts is obtained.
