The present disclosure provides a decoding method, a decoding device, and a readable storage medium, which include performing an exclusive-or logic operation on a first identification bit and a second identification bit in a first bit stream to obtain a first operation result, and processing the first bit stream according to the first operation result to obtain a second bit stream; performing the exclusive-or logic operation on a third identification bit and a fourth identification bit in the second bit stream to obtain a second operation result, and processing the second bit stream according to the second operation result to obtain a third bit stream; and deleting two specific bits in the third bit stream to obtain a decoded bit.
