Channel emulation of low-speed PLC transmission channels

Test and verification of the physical layer of power line communication systems are very difficult to accomplish, because the mains grid exhibits stochastic and time variant behavior. In this paper, we propose a channel emulator that allows for emulating a freely configurable PLC channel scenario in the frequency range between 9 kHz and 500 kHz. The emulator can be deployed for system verification during the design and development phase as well as for standardization purposes.
