In order to encode the parameters of sinusoidal model , the vector quantization techniques for amplitude parameters and the differential quantization for frequency parameters are proposed and discussed . at the same time , the frequency bin model , the random phase model and the zero phase model are also discussed 針對正弦模型參數的量化編碼,提出了幅度參數矢量量化、頻率參數差分量化等方法,并探討了頻率盒量化模型以及隨機相位和零相位模型等。
