© 2021, International Association of Engineers. All rights reserved. Coded power line communication (PLC) promises significant enhancement to the overall system performance over uncoded PLC systems. Yet, there is limited contribution on the theoretical analysis of coded OFDM-PLC systems. In this letter, the β β2/1 and β 1 β/β21 NB-Convolutional (Non Binary) codes have been examined in an extreme PLC environment and an investigation of the performance analysis in terms of bit error rate (BER) of coded orthogonal frequency-division multiplexing (OFDM) PLC systems has been carried out. This analysis is accomplished with consideration of the realistic PLC frequency multi-path channels and for variant values of the background to impulsive noise ratio Γ. Finally, a fair comparison of the BER performance of β β2/1 NB-convolutional code with (1; 7=5)8 binary code is carried out.
