Abstract:This paper proposes a hardware implementation scheme for the fractal modulation and demodulation system based on Mallat algorithm and polyphase filter, and the shaping and synchronization system are also designed. According to the weakness of false synchronization and high sensitivity to timing error, the carrier phase recovery is combined with frame synchronization on the basis of maximum likelihood (ML-) estimation, and at the same time the false synchronization can be detected and corrected. The simulation results indicate that the scheme is feasible and effective.
