- W2379851504 abstract "According to the wireless transmission characteristics in mine tunnels,a tunnel integrated attenuation model was proposed.The attenuation model is composed of two parts:large-scale fading,including pass-loss and shadowing,and small-scale fading,including multi-path and Doppler shift.The accuracy of the proposed model was supported by the match between analytical results and testing data.Based on the integrated attenuation model,the bit error rate(BER) performance by distance of many transmission technologies including Orthogonal Frequency Division Multiplexing(OFDM),Multiple Carrier Code Division Multiple Access(MC-CDMA),MC-DS-CDMA,DS-CDMA and MT-CDMA,were simulated.Simulation results indicate that spread frequency(SF) systems,e.g.MC-CDMA,have better performances in the case of short distances.When the distance is increased,especially before the breakpoint of the model,the BER performances of those SF systems are dramatically declined because of the increased multi-path time delay.By contrast,OFDM system can effectively overcome multi-path fading,leading to a better BER performance in the case of long distance.Therefore,OFDM technique is suitable for the long distance communication in mine tunnels,while SF based techniques are appropriate for short distance environment." @default.
