Abstract

The present invention puts forward a pipeline polar code encoder, comprising log<2>N groups of delay encoding modules which are connected successively, wherein each delay encoding module comprises one XOR-passing gate and a plurality of delay units which are connected with each other, wherein the N is the number of digits of the polar code encoder. The pipeline polar code encoder of the present invention, according to the principle of a folding technology, achieves encoding of polar codes through adoption of successive connection of the delay encoding modules consisting of the delay units, the XOR-passing gates and so on. The pipeline polar code encoder effectively reduces complexity of hardware, improves encoding speed and processing frequency, and has huge potential in actual application.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a pipeline polar code encoder. Background technique [0002] Since the 1980s, the rapid progress of communication technology has brought human society into the information age. The continuous development of wireless mobile communication technology provides a powerful impetus for the process of global informatization. Wireless cellular mobile communication has gone through: first-generation analog communication technology, second-generation digital communication technology, third-generation CDMA broadband communication technology, and has now entered the stage of industrialization and commercialization of 4G systems. While 4G technology is being promoted to industrialization and commercialization, mobile communication after 4G has entered the agenda, and the evolution and development of wireless mobile communication is facing new challenges. With the popularizatio...
