ABSTRACT:
An adaptive equalizer comprising a computing unit which receives a known signal sequence to estimate transmission channel characteristics and effect compensatory control of tap coefficients by use of a first algorithm that has fast convergence property, and a tap coefficient computing unit for making compensation for relatively slow changes in a random data input after the compensation for the transmission channel characteristics, which either employs an algorithm that involves a relatively low computational complexity or intermittently executes computation which contains an interpolation of consecutive sets of tap coefficients between intermittent intervals.
