| 摘 要： | 利用正交频分复用技术（OFDM）作为煤矿井下中压电力桥集器的核心技术，并相应提出了一种基于实数值遗传算法的改进部分传输序列（PTS）算法和基于SC算法的定时同步改进算法来加强通信的实时性与准确性，对中压电力桥集器的硬件系统的实现做了初步设计。经仿真结果证明，同其他优化算法相比，收敛速度更快，定时估计精度更高，系统性能得到明显的改善。

| Abstract: | This paper is based on Orthogonal Frequency Division Multiplexing（OFDM） technology, which is the core of the coal mine underground medium voltage electric bridge set technology. And to enhance the real-time and accuracy of communication, it puts forward the Partial Transimt Sequence（PTS） algorithm based on real numeric genetic algorithm and the timing chronization algorithm based on SC algorithm. It completes the preliminary design of medium voltage electric bridge set hardware system. The simulation results show that compared with other optimization algorithm, the convergence speed is faster, the timing estimation precision is higher, the system performance has been improved obviously. |
