Abstract  Abstract

In one embodiment, a method for generating a highband excitation signal includes harmonically extending a spectrum of a signal based on the lowband excitation signal; Calculating a time-domain envelope of the signal based on the low band excitation signal; And modulating a noise signal in accordance with the time-domain envelope. The method also includes combining (A) the harmonic extended signal based on the harmonic extended result and (B) the modulated noise signal based on the modulation result. In this method, the highband excitation signal is based on the result of the combining.
