IDENTIFICATION OF THE CHANNEL FREQUENCY RESPONSE USING CHIRPS AND STEPPED FREQUENCIES |
摘要 |
The transfer function of the communication channel in a mud pulse telemetry system is determined by sending a known signal through the channel and spectral analysis of the received signal. The known signal may be a chirp signal or a stepped frequency signal. Based on the determined transfer function, operating parameters of the pulser are adjusted. |
