Wideband Wireless Communication

Ultra-wideband wireless communication technology is brought, in the coal mine communications in this paper in order to raising the safe level of communication in coal mine. Ultra-wideband wireless communication is a system which is transmitted by the extremely narrow pulse transmission. An avalanche transistor is the core of extremely narrow pulse circuit. Narrow pulse wave form can be simulated by multisim software. Acquiring the results of simulation is the extremely narrow pulse whose pulse amplitude ranging from 10 v to dozens v and pulse width is about 3 seconds. In addition to this circuit carries on the theoretical analysis, the results is quite consistent with the simulation value in this paper.
