Abstract
A method of realization of adaptive equalization and an adaptive equalizer. The adaptive equalizer comprises an equalizer unit, which is used for equaling an input signal according to a compensation coefficient to obtain an output signal; a sampling comparison unit, which is connected to an output of the equalizer and is used for sampling a comparison result of the output signal of the equalizer and a reference voltage corresponding to reference voltage step; a data processing unit, which is connected to the sampling comparison unit and the equalizer unit. It is used for scanning a reference voltage step to determine range of the reference voltage steps to which step the amplitude of the output signal is corresponding; and scanning a compensation coefficient step, and determining the compensation coefficient for equalization according to the range of reference voltage steps. The solution of the present invention resolves such problems as long adaptive adjustment time, algorithm complex and large power consumption of the existing self-adaptive equalization algorithm.
