Abstract

The invention aims at providing a channel polarization secure coding method based on robust soliton distribution, and the method comprises the following steps: firstly, a sending end codes to-be-sentinformation based on robust soliton distribution; then, Polar coding is executed for the to-be-sent information which is coded based on robust soliton distribution; and a normal receiving end and an eavesdropping end respectively perform Polar decoding for the received information, finally, the normal receiving end and the eavesdropping end respectively perform belief propagation decoding for thereceived information subjected to Polar decoding, and restore the sent information. Compared with the existing technology, the method provided by the invention can improve transmission rate of information transmission while guaranteeing security and reliability of information transmission under the premise of slightly increasing secure coding and decoding complexity, and consequently improves validity of information transmission.

Description

technical field [0001] The invention belongs to the technical field of wireless physical layer channel coding, and relates to a coding method for ensuring safe information transmission in wireless communication, in particular to a channel polarization safe coding method based on robust soliton distribution. Background technique [0002] Safe, reliable and fast data transmission are the three basic elements in wireless communication. How to ensure the safe transmission of data on the basis of fast and reliable transmission has become a hot research topic in wireless communication in recent years. Traditional wireless data security transmission is based on cryptography theory, and its security is based on computational complexity. However, with the rapid increase of computing resources available to human beings, the traditional secure communication methods based on cryptography theory are facing great challenges. The physical layer security method proposed in recent years is ...
