ABSTRACT:
An adaptive equalizer is provided with an equalizing assembly for equalizing an input signal having a transmission frame which includes a first training field and a second training field. The input signal is temporarily stored in a storage unit and simultaneously subjected to equalization by the equalizing assembly. An equalization error in the second training field is calculated and compared with a predetermined value. When the equalization error exceeds the predetermined value, the equalizing assembly is reset to do the equalizing operations over again from the head of the second training field, using the input signal stored temporarily in the storage unit.
