Study on a voice hiding algorithm in GSM communication
全球移动通信系统中语音信息隐藏算法的研究

A voice hiding algorithm that can be used in Global System for Mobile Communication (GSM) was proposed.It is speech-hiding algorithm based on the Analysis-by-Synthesis Energy Ratio.The algorithm is based on the technique of Analysis-By-Synthesis (ABS) and can adjust adaptively the strength of the security information component according to public speech to achieve the best performance of hiding and encoding.
