- There exist many kinds of electromagnetic interference sources in a small and enclosing underground coal mine work area, which could lead to that the instable phenomenon of the wireless monitoring and communication systems constantly occur. Focused on the randomness of occurrence and duration of electromagnetic interference and the diversity of interference frequency band in underground coal mines, a kind of anti-electromagnetic method based on full duplex(FD) cognitive radio was presented. In present work, the transmission parameters such as transmission power and carrier frequency at each communication node(CN) can be easily adjusted by detecting the surrounding electromagnetic environment at correspondent CNs. When the frequency band being used by CNs is disturbed, the communication task can be kept by switching to other available frequency bands. By doing this, the whole network can be reached the approximation of optimal communication status. The simulation results show that the present method can obtain higher network efficiency by effectively avoiding frequency bands that are subjected to electromagnetic interference or cause data transmission conflicts. Furthermore, the anti-interference ability and the spectrum utilization efficiency of wireless communication systems in underground coal mines are obviously improved.
