摘要/Abstract

摘要： This paper applies wireless relay technology to improve bit error rate (BER) performance of ultrawideband
(UWB) system in coal mines, and studies optimal relay deployment strategies for the lowest BERs
in different coal mine environments. The multipath propagation environment in coal mines and the resultant
BER performance for single-hop UWB links are discussed. Without increasing the transmission energy, BER
performance for multi-hop relaying based UWB transmissions is analyzed. Using the multi-hop relaying, a
decoding-and-forwarding (DF) based UWB transmission scheme is proposed. Simulation results show that,
compared with traditional single-hop UWB transmissions, the proposed method can achieve 35 dB BER
performance gain in various coal mine environments without extra energy consumption.
