Abstract :
Digital matched filters (DMF) is adopted to achieve frame synchronization in soft-decision channel for turbo decoder. The realization architecture of DMF is studied. According to CCSDS standards, the frame acquisition circuit for turbo codes system is designed. Experiment results indicate that, the circuit designed in the paper is suitable for the acquisition requirement of turbo codes system and can be used in the frame synchronization of other soft-decision channel.
