Improved 4-kbit/s PSI-CELP coding using pitch and phase adaptation

研究成果: Paper › 査読

抄録

An improved 4-kbit/s PSI-CELP coding method called phase-adaptive PSI-CELP has been developed; it uses a new adaptation method to generate random excitation. This adaptation method not only gives pitch periodicity to the random excitation but also synchronizes the basic point of the stored random vector with the pitch phase. The quality of this coding method is superior to that of CELP and conventional PSI-CELP.
