Abstract

When the filter bank is operated, the problem of the boundary region of the filter bank occurs. In this paper, we propose a new design method of a filter bank that dose not produce the error in the boundary region. First, we show a design method of the first order inverse system with subband structure and the problem of the design method. Then we show a new design method of the filter bank that does not produce the error in the boundary region. And, a nonlinear inverse system is constructed by using the filter bank designed by this method and eliminate the nonlinear distortion. The proposal method realizes that the error of boundary region can be decrease and the nonlinear distortion can be decreased by 72dB or less.
