The performance of OFDM-based NB-PLC systems, in terms of AEC, has been investigated in this paper.
We first reviewed the noise characteristics of NB-PLC and subsequently introduced and derived the expression for the AEC.
Based on long-term measurements in the field, the performed simulations confirm the accuracy of the derived expression for the different tested periods.
Some frequency sub-bands have shown a higher ergodic capacity than others, which confirms the effects of channel selection on OFDM-based NB-PLC systems performance.
In our future work we will propose and evaluate new techniques to enhance the OFDM-based NB-PLC systems.
