Summary

A pulse-based data telemetry technique is suggested in this paper, which aims at the suppression of the residual tail of oscillations that naturally follows the response of an ultrasonic transducer to a rectangular pulse. This is made possible by the introduction of a line encoding scheme that suggests the use of an excitatory/inhibitory complex rather than a single excitatory pulse. Efficacy of the technique suggested in this paper was verified through modeling and testing a complete ultrasonic data telemetry link including the transmitting and receiving transducers, as well as the signal conditioning and data recovery blocks on the receiver side.
