Abstract
A method for configuring telemetry transmission includes receiving a transmitted telemetry signal at the earth's surface. The received signal is selected and processed to compute a measured power spectral density (PSD). A theoretical PSD is computed of the transmitted signal at the known carrier frequency and processed in combination with the measured PSD to compute an attenuation factor of the transmitted signal at a plurality of frequencies.
