“…OFDM is a multi-carrier modulation largely employed in wired systems, Power-Line Communications (PLC) [ 22 , 23 ] and wireless standards systems (e.g., Digital Video Broadcasting-Terrestrial (DVB-T) [ 24 ], Wimax, IEEE 802.11a/g/n/ac [ 25 ]). The high data rates and robustness to combat multi-path fading make OFDM a perfect candidate for reflective industrial environments [ 26 ].…”

The importance of synergy with industry lies in the possibility of experimental validation of the work research results. With Software-Defined Radio (SDR) platforms, it is possible to implement a physical layer and to have tests with hardware in a real environment. In this paper, we investigate the validation of an impulsive noise resistant physical layer based on Orthogonal Frequency Division Multiplexing (OFDM) and an interesting concatenation of forward error correcting codes: Rank metric Code (RC) and Convolutional Code (CC). We fully design and implement a new block namely RC Encoder + WiFi Mapper in GNU Radio, which acts as a forward error correcting code to mitigate impulsive noise occurring in substations. After showing by simulations that using this coding scheme is very efficient in mitigating the bursty nature of impulsive noise, we then confirm that the same performance is maintained even with various impulsive voltages and experimental scenarios, which confirms the high performance of the proposed approach.
