“…On the other hand, the decoding process of the QC-LDPC codes can be performed by using soft-and hard-decision decoder schemes similar to LDPC codes (Chen, Dholakia, Eleftheriou, Fossorier, & Hu, 2005;Gallager, 1963;Jiang, Peng, Song, Pan, & Yang, 2009;Phakphisut, Supnithi, Sopon, & Myint, 2011;Zhong, Xu, Xie, & Zhang, 2007). Although hard decision decoders have the advantage of low complexity, they always exhibit lower performance than that of soft decision decoders.…”

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 parameters such 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.
