| 摘 要： | 主要研究了基于IEEE802.11a的矿井无线通信系统同步算法,并用Matlab对其基带形成和接收过程进行建模,提出了一套比较完整的针对IEEE802.11a前导结构的定时同步算法和频率同步算法。在不同的信道特性以及不同信噪比的情况下对同步性能进行了仿真。结果表明所提出的算法不仅具有低复杂度的可实现性,而且有很好的精度。

| Abstract: | The paper mainly studies the synchronous asthmatic for the mine wireless communication system bosed on IEEE802.11a, and builds the model of the baseband formation and the receiving course, and proposes a relatively complete set of the timing and frequency synchronization algorithm for the IEEE802.11a leading structure. Meanwhile, the simulations are carried on in the conditions of the different channel characteristics and the different signal-to-noise ratio. The results show that the promoted algorithm char... |
