摘要：
Disclosed is an apparatus and a method for actively adjusting the quantization interval of signals inputted to a decoder in a digital communication system. The apparatus includes a quantization level generator for measuring a dynamic range of received packet data and calculating a corresponding scale factor, and an input signal converter for scaling a received data signal according to the scale factor so as to output a quantized signal.
