Embedding the encryption module in the bluetooth terminal can realize the secure transmission of voice on the mobile phone and the mobile communication network. Aiming at the problem of bluetooth encrypted speech synchronization, the initial synchronization header and the periodic synchronization header are designed by using the sinusoidal signal time domain feature extraction and the transparent transmission of the waveform codebook. The initial synchronization establishment scheme and the voice synchronization detection recovery scheme are proposed. Simulation experiments and analysis show that the scheme has less time overhead and computational overhead, and that the scheme can effectively achieve initial synchronization, synchronous detection and recovery.

Key words: mobile communication, bluetooth, voice synchronization, sinusoidal signal, waveform symbol
