摘要
PURPOSE: A method for sinusoidal waveform synthesis is provided to use a weight as a sinusoidal wave value, a method for applying phase conversion recognition, and a method for estimating a sinusoidal parameter by applying a reduction harmonic size parameter. CONSTITUTION: An overlapping and adding harmonic composite device extracts a sinusoidal parameter in a maximum overlapping point between k th and K+1 th frames(S130). The device controls a phase level of a synthesis sinusoidal wave(S150). The device predicts a current frame from a previous frame(S170). The device predicts the size of a sinusoidal wave which will be used as a weight. The device performs modeling of the synthesis sinusoidal wave(S190).
