Broadband Characterization of Indoor Powerline Channel

For data communication over any medium, it is necessary to determine the characteristics of the communication channel. Powerline channel has been considered as a medium not only for low-rate, control purpose communication, but also for high-speed data communication, such as home networking and Internet access. In order to implement advanced communication technologies, the complete knowledge of the broadband powerline channel is required. This paper strives to widen understanding of broadband indoor powerline channel. We study the properties of mains cable and indoor PLC channel via their scattering parameters (S-parameters). Also, noise and interference of a PLC channel are measured in frequency domain.
