Abstract

Overføringsfunksjonen til kommunikasjonskanalen i et slampuls-telemetrisystem bestemmes ved overføring av et kjent signal gjennom kanalen og spektralanalyse av det mottatte signalet. Det kjente signalet kan være et chirp-signal eller et signal med trinnvis frekvens. Basert på den funnede overføringsfunksjonen justeres pulsatorens kjøreparametere.The transmission function of the communication channel in a mud pulse telemetry system is determined by transmitting a known signal through the channel and spectral analysis of the received signal. The known signal may be a chirp signal or a step frequency signal. Based on the found transfer function found, the driving parameters of the pulsator are adjusted.
