Problems solved by technology

While performing random interleaving for polar codes is the best way in theory, it is not feasible in practice
In addition, if the overall interleaving is performed on the polar code bit sequence, in the decoding process of the receiving end receiving the polar code bit sequence, it is necessary to completely receive the interleaved polar code bit sequence before deinterleaving can be performed, resulting in interleaving The encoding and deinterleaving process takes a long time, resulting in increased data transmission delay and excessive processing overhead

Abstract

The present invention relates to a polarization encoding method, a polarization encoder using the same, and a wireless communication device. The polarization encoding method includes the following steps that: polarization encoding is performed on a bit sequence to be encoded, so that a polarization code bit sequence can be generated; the polarization code bit sequence is divided into a plurality of groups according to a predetermined rule, wherein each of the plurality of groups includes corresponding polar code bit subsequences; and in each of the plurality of group, the corresponding polar code bit subsequences are interleaved, so that an interleaved polar code bit sequence can be generated.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, the present invention relates to a polar encoding method, a polar encoder using the polar encoding method, and a wireless communication device. Background technique [0002] In modern communication systems, channel coding is usually used to improve the reliability of data transmission, so as to ensure the quality of communication. Polar code (Polar Code), as the only channel coding technology that can be theoretically proven to reach the Shannon limit and has practical linear complexity coding and decoding capabilities, has become an important channel coding scheme in the next generation communication system 5G. [0003] In order to adapt to channel fading and high-order modulation, it is necessary to interleave the polar code bit sequence to realize discrete and correct burst errors caused by fading channels, and improve the transmission characteristics of co...
