Abstract

Aiming at the problem that the Bluetooth voice signal cannot be transmitted through the voice channel after being encrypted, this paper established a Bluetooth voice encryption data transmission model, and proposed a waveform codebook generation algorithm for Bluetooth voice encryption transmission. The algorithm used subcarrier modulation to generate the initial modulation codebook, and trained data to obtain the demodulation codebook. It designed the particle-pair algorithm with the last elimination mechanism to find the optimal codebook. Simulation analysis shows that the proposed algorithm has the advantages of fast convergence rate and can generate waveform codebooks with different bit transmission rate and low symbol error rate. Experiments show that using this waveform codebook to transmit data in Bluetooth has low symbol error rate.
