摘要
正交频分复用(OFDM)技术已成为未来宽带和广带高速数字无线通信的核心技术.模拟空直巷道和分支巷道的井下实际环境,研究OFDM调制技术在矿井巷道中的宽带无线通信性能.
Orthogonal Frequency Division Multiplexing（OFDM）has become the core technology of broadband and wideband high-speed digital wireless communication.We simulated the physical environment of empty straight tunnel and branch tunnel,and studied the performance of wide band communication systems which used OFDM modulation technology under the special confined space of mine tunnel.
