Blind Equalizer with Noise Reduction Function

Recently, in order to compensate for distortion of the received signals, the blind equalization method has been studied. The blind equalizer is designed by using only received signals. However, equalization precision is lower when noise is included in the received signals [1]. Therefore, in order to solve the problem, we propose a method to equalize accurately even in the noisy environment by using Total Least Squares (TLS). Specifically, the procedures of equalization with noise reduction function are as follows:
