| 摘 要： | 针对目前煤矿井下无线通信的状况，提出一种基于STBC—OFDM技术的井下宽带无线数据传输系统，并重点针对物理层的关键技术进行了分析和仿真。该系统可以为多种井下终端设备提供一个通用的宽带数字传输平台。理论分析和仿真实验均证明该系统不仅可以提供更高的传输速率，而且可以有效抵抗衰落的影响，扩大有效通信范围。

| Abstract: | An underground mine broadband wireless communication system based on the existing WLAN structure is proposed, And the techniques of STBC and OFDM used in the physical layer are analyzed and simulated. The proposed system can provide a general data transmission platform for all kinds of underground mine terminal equipment . Both the analysis and simulation verify the fact that the proposed system can not only support higher transmission rate, but also combat effectively the fading and extend the communication distance. |
