Power line communication (PLC) is one of the most attractive communication methods for in-home networks. However, the emissions of unwanted electric waves from PLC system, noise, inter-symbol interference (ISI) and inter-channel interference (ICI) cause harmful interference to communication systems. This paper discusses the characteristics of underground(More)
This work presents an underground coal mine channel model for the broadband characterization of low-voltage power lines. The model is characterized by taking into account both measured and geometrical channel characteristics and can easily be used to take into account also the presence of noise. The channel is described by a conventional multipath(More)
In this paper, the channel of the underground coal mine (UCM) PLCs is analysis, which indicates the UCM PLCs is more complex than home PLCs and this channel can be described with multipath characteristics and strong noise interference characteristics. Accurate modulation should be adopted. Conventional OFDM and Wavelet OFDM are compared by focusing on two(More)
