Abstract

Narrowband PLC channel emulators are devices used to test PLC transceivers without the need for the latter to be connected directly to the hazardous and erratic power lines. It is also more cost effective and faster than simulators. The state-of-art NBPLC channel emulators have been implemented on the hardware using impulse response. While this is much simpler than the frequency domain approach, however, it is slower especially when it involves a large set of coefficients. For most designs, higher transform points would require a large size of coefficients, where normally, an external device like a PC or DSP is needed to generate the coefficients. In this paper, a standalone FPGA is used to implement the channel emulator by operating the emulator in the frequency domain.
