Abstract  Abstract

(57) (Abstract) The high frequency component of a wideband signal that was downsampled during encoding in the past is recovered, and during decoding, this high frequency component is injected into an oversampled composite version of the wideband signal to provide a full In a method and apparatus for generating a synthesized broadband signal of a spectrum, a white noise generator generates a white noise sequence. The series-connected gain adjustment unit, spectrum shaper, bandpass filter relates to a set of shaping parameters indicative of the downsampled wideband signal, such as voiced sounding factor, energy scaling factor, tilt scaling factor, linear prediction filter scaling factor, etc. , Spectrally shape the white noise sequence. The signal injection circuit ultimately injects the spectrally shaped white noise sequence into the oversampled composite signal version, thereby generating a full spectrum composite wideband signal.
