Funding Information:
Lucas Giroto de Oliveira was with the Digital Communications Group at the University of Duisburg-Essen, Germany, from 2015 to 2016 with a Science without Borders (CsF) scholarship funded by the Brazilian federal government. He received the B.Sc. and the M.Sc. degrees in Electrical Engineering with a major in Electronic Systems from the Federal University of Juiz de Fora, Brazil, in 2017 and 2019, respectively. Since 2019, he has been as a research associate with the Institute of Radio Frequency Engineering and Electronics, Karlsruhe Institute of Technology, Germany, where he is also pursuing the doctoral degree. From April 2019 to March 2021, he was also a recipient of the research grant for doctoral programmes in Germany from the German Academic Exchange Service (DAAD). His research interests are in the areas of signal processing, digital communication, and their applications to radar systems, specially multiple-input multiple-output radar-communication systems and radar networks.

N2 - This study discusses key characteristics and benefits of using time-domain reflectometry (TDR) systems based on the Hermitian symmetric orthogonal frequency-division multiplexing (HS-OFDM) scheme for fault detection and location in power distribution networks. In this context, a system model with power line modems injecting signals and capturing reflections in a power distribution network is outlined. Next, two reflectogram processing approaches, namely digital pulse compression and channel estimation, are examined. Also, the effects of different parametrizations and multiple access schemes on the performance of the HS-OFDM-based TDR system are addressed. Numerical results confirm that HS-OFDM-based TDR systems making using of channel estimation outperforms their counterparts based on pulse compression. The frequency range for narrowband power line communication provides fair range resolution and maximum unambiguous range values. Also, it is seen that the use of frequency-division multiple access schemes implies different signal-to-interference-plus-noise ratio (SINR) performance among different power line modems (PLMs) connected to a power distribution network. Time-division and code-division multiple access schemes, on the other hand, provide fair SINR performance among the PLMs at the cost of obtaining a small number of reflectograms during a time interval.
