Abstract: The invention discloses a wireless measurement-while-drilling system polarization channel coding method based on a Gray code structure, and the method comprises the steps: constructing a polarizationchannel coding method according to the structure of a Gray code, and the coding method being used in a channel coding module of an underground instrument of a wireless measurement while drilling system; designing a continuous cancellation list (SCL) decoding algorithm according to a channel coding method of an underground instrument, and then applying the algorithm to a decoding module of a groundinstrument of a wireless measurement while drilling system to recover underground sent data. The method has the advantages that the constructed polarization channel coding method has a Gray code structure and has better error code performance than a common polarization code, so that the potential of the polarization code is further excited, the bit error rate of the wireless measurement-while-drilling system is effectively reduced, and the reliability of the system is improved.
