摘　　要：针对煤矿井下低压电力线的传输特性,提出了基于CLUSTER-OFDM的信号提取和传输技术,建立了其数学模型,同时建立了基于CLUSTER-OFDM的煤矿井下子群分配机制。通过仿真和实验验证了CLUSTER-OFDM信号提取和传输技术的可行性,实验结果表明该技术对消除OFDM技术峰均功率比过大有一定的改善,提高了用户接收信号的可靠性。Aiming at the transmission characteristics of coal mine low - voltage power line, this article proposes the signal extraction and transmission technology based on CLUSTER - OFDM. It also establishes its mathematical model, and establishes the eoal mine sub- group distribution mechanism based on CLUSTER - OFDM. According to the simulation and experiment, it proofs the feasibility of the CLUSTER -OFDM signal extraction and transmission technology. The experiment results show that the technique had some improve- ment for the elimination of peak to average power ratio of OFDM technology, which improves the reliability of the received signal of the users.
