Abstract :
We propose a noisy-channel model for a capacitively-coupled personal-area network (PAN) with megahertz-frequency signals. The model describes the influence of power lines connected to transceivers. We analyzed the signal-to-noise ratio (SNR) for the PAN channel. It is derived from the model that the SNR can be enhanced by using a common-mode choke. We also found conditions for enhancing the SNR. The validity of the model and analysis are confirmed by experimental results.
