Transceiver circuit design based on OFDM technology for well-logging cable telemetry system

In order to realize application of OFDM technology in the high-speed cable telemetry system, this paper detailedly designs the data transceiver circuits of both ends of the well-logging cable. The high-speed data processor, the low-power and high-precision electronic devices were selected in this design. The designed circuit system allows data to be transmitted stably at the rate of no less than 1 Mbps through the 7000 m well-logging cable. In addition, the circuit can meet well the special requirement of well-logging application environment, such as small size, high temperature endurance, etc.
