摘　　要：本文提出采用正交频分复用调制技术应用于煤矿通信系统,同时多址接入方式使得该技术尤为适用于煤矿数字通信系统的设备制式多、区域分布广、调制技术不一致等复杂情况。正交频分复用调制技术实现高速数据传输的试验,证明该技术进行信息传输在一定条件下是可行的。In this paper, the modulation technology of orthogonal frequency division multiplexing （OFDM） is put forward. At the same time, the application of multiple access modes makes the technology especially applicable to the digital communication system of coal mine in complicated circumstance such as more equipment modes, broad region distribution and different modulation technologies. By the experiments about realizing high-speed data transmission according to OFDM modulation technology, the results verify that the information transmission using this technology is practicable under certain conditions.
