| Abstract: | Sub-band coding of the frequency domain cod-ing,inaccordance withsub-band coding of this frequency domain characteristics,we can use filter to divide the se-cret voice signal into sub-band high-frequency and low frequency sub-band,and then the secret information em-bedded in voice low-frequency sub-band,to achieve the objective of the secret transfer. |
