| Abstract: | This paper proposes the design of a symbol and carrier synchronizer for Chinese DTrB system. The implementation architecture based on FPGA is also introduced, which solves the symbol synchronization problem under large carrier offset. The simulation performance shows that our design can work stably and is easy to implement. |
