Abstract:
An adaptive equalization method of generating a pseudo send electrical signal composed of pieces of pseudo transmission electrical data, from a received electrical signal composed of plural pieces of received electrical data, to thereby reduce noise and signal distortion components in the received signal, comprising:receiving the signal composed of plural pieces of received data; andgenerating (nD)th pseudo transmission data based on (nD)th received data x(nD) through (nD+D-1)th pseudo transmission data based on (nD+D-1)th received data x(nD+D-1), under the condition of L<D, by using a tap coefficient C(nD) calculated by the following equation: ##EQU8##where C(nD) and C(nD-D) are tap coefficients used to generate nth pseudo send data, n and D being integers equal to or grater than 1, .mu. is a step size, which is a real number, L is the number of data added, which is an integer equal to or greater than 2, e(nD-i) is an error contained in (nD-i)th pseudo transmission data and x(nD-i) is (nD-i)th received data.
