“…In that impulse response was used to compute the transfer function, which also takes into account for number of branches in the power line network. The present work, leaved the top-down approach used in [12] because of lack of resources and sufficient data. The present work is closely related to [13] where medium voltage overhead lines are characterized based on transmission matrices for 3 wire powerlines.…”

Due to the increasing importance of communication networking, the power line (PL) channel has been considered as a good candidate for the communication medium. Power line communications (PLC) term stands for the technologies for the data communication over the electrical power supply network. The PL channels were not designed to transmit high speed data; therefore, they exhibit hostile medium for communication signal transmission. There are many factors such as noises, attenuation, distance, etc. affecting the quality of the transmission over PL channels. This paper presents PL model in the first sections of the work. Then it covers the security assessment of the PL system in the supervisory control and data acquisition (SCADA) context.

Comparison of Passband and Baseband Transmission Schemes for Power-Line Communication OFDM Systems

Passband and baseband transmissions are two competing transmission schemes for power-line communication (PLC) orthogonal frequency-division multiplexing (OFDM) systems. The advantage of the former is that it is simpler to implement for digital circuits as it needs the half-size inverse fast Fourier transform/fast Fourier transform. As will be shown, there are synchronization errors, such as carrier frequency offset (CFO) and sampling frequency offset (SFO) that degrade the performance of passband transmission. On the other hand, baseband transmission is expected to be less complex in an analog circuit implementation and to be affected by only SFO, since it does not need up-down conversion. Both CFO and SFO are caused by the frequency errors of the reference clocks in the transmitter and receiver. In this paper, signal-to-interference-plus-noise ratios and capacities are considered in comparing the effects of synchronization errors in passband and baseband transmissions. The results indicate that the performance degradation of passband transmission is almost the same as that of baseband transmission in the presence of synchronization errors.Index Terms-Baseband transmission, carrier frequency offset, channel capacity, orthogonal frequency-division multiplexing, passband transmission, sampling frequency offset.
