1. A system comprising:
a tubing positionable within a wellbore;
a first downhole communication device positionable to receive acoustic signals from the tubing and to transmit acoustic signals to the tubing; and
a computing device in communication with the first downhole communication device, the computing device comprising:
a processor; and
a non-transitory computer-readable medium that includes instructions that are executable by the processor to perform operations comprising:
receiving a test message comprising a spectral waveform from a second downhole communication device;
determining a desired reception frequency for receiving communications from the second downhole communication device using spectral data generated from the spectral waveform by:
identifying one or more pass-bands through which the test message is received; and
selecting the desired reception frequency from a particular pass-band of the one or more pass-bands using an algorithm that receives input comprising an area underneath each pass-band of the one or more pass-bands, amplitudes associated with the one or more pass-bands, a width of each pass-band of the one or more pass-bands, and a midpoint of the particular pass-band, wherein the particular pass-band has a highest amplitude, a highest width, or a highest area underneath the particular pass-band compared with other pass-bands of the one or more pass-bands; and
controlling the first downhole communication device to transmit a response message to the second downhole communication device identifying the desired reception frequency.
