A Construction Method of Partially Polarized Polar Codes

Abstract

The invention provides a construction method of partially polarized polar code, which belongs to communication technology field. The method cancels regularly unneeded polarization operation in polarization process of traditional polar code and deletes 1 that needn't participate in polarization operation in the original polarization matrix, which cancels polarization operation caused by raw information Bit in coding procedure. The generated polarization matrix after deleting 1 regularly is provided. On the one hand, partially polarized polar code generated by the method can improve error-correcting performance of finite length polar codes, and simplify polarization operation structure of polar code and reduce code-decode complexity of polar code; on the other hand, the polar code still can be proved to reach the channel capacity at infinity. A simulation result shows that the polar code has better BER performance than the traditional polar code.

Description

Technical field

[0001] The invention belongs to the field of communication technology, and specifically relates to a method for constructing a partially polarized polar code. Background technique

[0002] In 2009, Arikan announced the polar code channel coding theory to the world, and for the first time proved that polar code is the only error correction coding scheme that can theoretically reach the channel capacity. It has low coding and decoding complexity, flexible and simple, and extremely Easy to operate. During the period from November 14 to 18, 2016, at the 3GPP RAN1#87 meeting held in Reno, the United States, the polar code was clearly specified as a short code scheme for 5G channel coding applications.

[0003] As is well known in the art, the traditional polar code channel coding completes the channel error correction coding process through the polarization matrix. However, the traditional channel polarization theory does not differentiate between the polarization of e...
