An Enhancement of Channel Separability for Stereophonic Signals by Common Mode Rejection Method

동상분 제거에 의한 입체음향의 채널 분리도 개선

In this paper, we firstly suggested C&D (Common mode and Differential mode) model for the representation of a stereophonic signal. Then a measure of stereophonic channel separability is defined as the ratio of differential mode energy to total energy in frequency domain. After that, a new channel separability enhancement scheme is proposed by the control of common mode rejection. Finally, some experimental results are presented in order to verify our scheme.
