High speed telemetry system using transmission medium as a component of a telemetry link

摘要

The telemetry system allows a high speed transfer of digital data at for example 81,920 KHz, by utilizing the titanium can as a component of a telemetry link. The telemetry system includes a transmitter and a receiver that are interconnected by means of the telemetry link. Input data is fed to the transmitter where it is encoded, modulated, and transmitted through the can to the receiver. The can introduces a desired low pass filtering function that complements the signal encoding and modulation process implemented by the transmitter. The transmitter processes a binary data signal provided in Non-Return-to-Zero (NRZ) format. By a series of transformations, the transmitter produces a signal whose spectral properties closely match the telemetry link, including the titanium can. The titanium can becomes a source of controlled inter-symbol-interference (ISI) to be compensated for in the receiver.
