摘要
通过研究矿井下的无线通信环境,针对其中存在的多径衰落和传输速率低的问题,利用OFDM技术抗多径衰落、频谱利用率高等特点,以Xilinx ISE为软件开发平台,采用Xilinx Virtex-5 FPGA为硬件载体,对基于OFDM的矿井基带发送系统进行设计与FPGA实现。结果表明,作为一种稳定可靠的通信方式,OFDM技术可以应用于矿井基带发送系统中,研究结果具备一定的理论价值和实际意义。
The underground wireless communication environment in coal mine was studied.In view of the problems existing in un- derground wireless communication, such as multipath fading and low transmission rate,based on the characteristics of anti-mul- tipath fading and high spectrum efficiency of OFDM technology, a mine OFDM baseband transmission system was designed and implemented on FPGA using Xilinx ISE as software development platform and Xilinx Virtex-5 FPGA as hardware carrier, OFDM technology as a stable and reliable means of communication can be applied to mine baseband transmission system. ]＇he result of study is of a certain theoretical value and practical significance.
