Embodiments of the present invention provide an encoding method, a decoding method, an encoding device, a decoding device, an encoding system, and a decoding system, and the present invention relates to the field of communication, and is used to improve decoding performance and the accuracy of survivor path. The method comprises: encoding the information bit according to the first level encoding method, thereby acquiring a codeword after the first level encoding; acquiring a sort data value of each check bit in the codeword after the first level encoding, then adjusting each check bit to an appropriate position according to the sort data value of each check bit; the sort data value refers to the value of S when the check bit is relevant to former S information bits of the information bit in the codeword after the first level encoding; the value of S is an integer not equal to zero; according to the second level encoding method, encoding the codeword which after the first level encoding and adjusts the check bit position, and acquiring a codeword after the second level encoding. The present invention is appropriate to various communication systems. |
