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.

The field measurements were performed using the PL360 modem evaluation kit of Microchip.
The measurements of the noise were performed in the NB-PLC FCC band from 42 to 472 kHz, and they were segmented into eight sub-bands.
The measurement period lasted one complete week, with multiple measurement cycles.
The field test was conducted by connecting the measurement set in the meter box beside the metrology meter of a standalone villa in Doha

The PLC presents many advantages as presented in this graph.
However, similar to most communication systems, PLC suffers from channel
attenuation and additive noise as major transmission impairments.
In this paper, we present Ergodic Capacity Analysis of OFDM-based
NB-PLC Systems.
