This paper is based on Orthogonal Frequency Division Multiplexing (OFDM) technology, which is the core technology of the coal mine medium voltage electric bridge set. And to reduce the high peak-to-average power ratio arising from the OFDM signal and to strengthen the timeliness and accuracy of communication, it puts forward a real-valued genetic improvement of Partial Transmit Sequences Algorithm (RVGA-PTS) and the Timing Synchronization Algorithm which is based on SC algorithm. Finally, it completes the preliminary design of hardware system for the medium voltage electric bridge set. The simulation results show that compared with other optimization algorithm, the convergence speed is faster, the timing estimation precision is higher, and the system performance has been improved obviously.
