Abstract

Optimized frequency tones for the power line channel is presented from an experimental scenario. Four sets of frequency tones, grouped according to CENELEC´s regulation on frequency use for narrow band power line applications are selected according to their signal-to-noise ratio (SNR) performance. COMBLOCKS, a prototyping hardware was used for the implementation. Often times, M-FSK/OFDM have been presented and used as the modulation scheme of choice for power line communications (PLC), the choice of best frequencies to use is however, an area that has hardly been explored. This paper is concentrated on the choice of such optimal frequencies.
