ABSTRACT:
A method and apparatus is provided for adjusting the tap coefficient of an adaptive automatic equalizer having a plurality of tap registers. An input signal is repetitively applied to a train of tapped delay elements and the sum of the weighted output of each tap output is obtained. An error output is obtained by taking the difference between the sum of the weighted output of each tap output and a reference signal, and a correlation value is obtained between the error output and each tap output of the delay elements. The improvement comprises storing the tap weights of each of the tapped registers and obtaining the total sum of each tap weight of one of the registers wherein the tap weight of a tap is the correlation value. This step is repeated M times, where M is an integer so that the total sum of each tap weight in another of the tapped registers is obtained and the error output is added to the total sum, determining a value of tap coefficient by the final total sum after M adjustments of the most rapid equalization. The optimum coefficient is obtained by using the value of the tap coefficient for the most rapid equalization of the tapped registers and the weight of the taps of the delay element is revised by the optimum coefficient-weight-sum of the contents of the tapped register and the tapped delay elements, thereby adjusting the weight of each tap of the delay elements.
