Comparison on Reflectometry Methods for Wire Fault Location

Diagnosis of the ageing wiring systems in aircrafts, automobiles, industries, transportation, etc is essential. A wide variety of techniques are published in the literature claiming effective diagnosis of wire faults. The focus in this paper is limited to the techniques based on reflectometry principle. These are categorized in to Time Domain Reflectometry [TDR], Frequency Domain Reflectometry [FDR], Spread Spectrum Time Domain Reflectometry [SSTDR], Modified Spread Spectrum Time Domain Reflectometry [M-SSTDR], Noise Domain Reflectometry [NDR], Distributed Reflectometry[DR], Multi Carrier Reflectometry [MCR], Filterbank Multi Carrier Reflectometry [FBMCR] and Time Frequency Domain Reflectometry [TFDR]/Joint Time Frequency Domain Reflectometry [JTFDR] techniques. This paper presents a brief description of these techniques along with their comparison with respect to the key parameters and simulation results of Filter Bank Multi Carrier Reflectometry (FBMCR) technique.
