WINDOW PROCESSING METHOD AND APPARATUS FOR INTERWORKING BETWEEN MDCT-TCX FRAME AND CELP FRAME

摘要

The present invention relates to a window processing method and apparatus for interworking between an MDCT-TCX frame and a CELP frame. The window processing apparatus comprises: a coding mode decision unit for deciding a preceding subframe coding mode and a subsequent subframe coding mode, with respect to a current subframe; and a window application unit for applying a window that is determined according to the preceding subframe coding mode and the subsequent subframe coding mode, to the current subframe.
