Abstract

Many industrial applications need the technologies of power and data transmission through metal barriers without physical penetrations. The reverberation of the acoustic signals in the channel can produce multipath distortion with a significant delay spread that introduces severe inter-symbol interference into the signal. To overcome this shortage, we did a more detailed study of the channel's characteristics. The voltage transfer function and impulse response of the same channel were obtained. The response signal was used for system identification, and then a more accurate model of the ultrasonic channel was built. An equalizer was directly derived based on the identified model. The equalizer's superb results on echoes cancellation is simulated and verified using ASK modulation schemes in Simulink. The results show that data rates on the order of 100kbps at least. By choosing a discrete time representation of the system, the resulting equalizer is readily implemented on FPGA.
