Threshold-based Finite State Machine for Frame Synchronization in Variable Coding and Modulation System
Abstract— In this paper, we present a robust and real-time frame synchronization scheme for second
generation digital video broadcasting (DVB-S2) standard in Variable Coding and Modulation (VCM) system.
Variable frame lengths, large frequency offset and extremely low SNRs make it hard to obtain frame headers
in VCM. Our proposed scheme is based on differential detector and threshold-based finite state machine
(FSM) to achieve fast frame synchronization. Simulation results indicate that our proposed scheme shares
similar robustness with existing methods, while has low latency and implementation complexity than others.
