An analysis of blind equalization method using the orthogonal filter

On blind equalization for long impulse response, such as indoor sound, conventional blind equalizer using the FIR filter has problem which is slower convergence rate of the algorithm. To solve this problem, we previously proposed the blind equalizer using the orthogonal filter. But, in the paper, we confirmed the validity of the proposed algorithm through only computer simulation. Then, in this paper, we analyze the validity of the orthogonal filter in detail.
