DEVELI, Ibrahim  and  KABALCI, Yasin. Proposal of an experimental data and image transmission system and its possible application for remote monitoring smart grids. J. appl. res. technol [online]. 2017, vol.15, n.3, pp.303-310. ISSN 2448-6736.  https://doi.org/10.1016/j.jart.2017.03.001.

This paper investigates the bit error rate (BER) and the peak signal-to-noise ratio (PSNR) performances of quasi-cyclic low-density parity-check (QC-LDPC) coded orthogonal frequency-division multiplexing (OFDM) systems over an actual power line communication (PLC) channel that are acquired by performing very long-term experimental measurements from the grid. The examined system is tested by changing system parameter ssuch as code length, iteration number, coding rate and message type in detail. The results of this study show that the QC-LDPC coded OFDM system can be a possible solution for communication and remote monitoring purposes in smart grids.
