Abstract
PURPOSE:To remarkably reduce the delay time till the data output by shifting the maximum value of the initial tap gain shifted to each tap gain register to the data input side by a prescribed quantity. CONSTITUTION:A reception data is inputted to a control section 201 and a training signal is sent, then the initial value of the predetermined tap gain is loaded respectively to each register element of a tap gain register 150 from a memory 200. Then the equalizing processing by applying tap gain calculation is repeated by number of times of training decided in advance. In this case, the equalizing output signal is extracted from an adder 160 from the point of time when a first reception data is shifted up to a shift register 130 corresponding to the peak of the maximum value of the initial tap gain loaded to the register. Thus, the data output is quickened and the delay time is shortened.
