EXCITING SIGNAL GENERATOR, VOICE CODER, AND VOICE DECODER |
| 摘要 |
An MA adaptive code vector is generated by using a finite number of noise code vectors used in the past, an adaptive code book gain, and a pitch period, and the amount of phase shift is calculated from the MA adaptive code vector, thereby shifting the phase of the noise code vector by the calculated amount of phase shift.
