Problems solved by technology

[0003] In the prior art, there is a problem that the complexity of the polar code construction is too high. Although the prior art has proposed some methods that can reduce the complexity of the polar code construction, it is not difficult to find that the final complexity is still O (N) magnitude
This means that when the frame length is relatively long, the complexity reduction of the existing technology will be very limited

Embodiment Construction

[0025] The concept of polar codes was first formally proposed in 2009, but it can be traced back to the research on channel polarization phenomena as early as 2006. We take a symmetric binary input discrete memoryless channel (B-DMC) as an example To illustrate the phenomenon of channel polarization. For a given symmetric binary input discrete memoryless channel W: Record its state transition function as W(y|x). The so-called symmetric B-DMC exists for the channel The bijection π on makes W(y|x) satisfy W(y|0)=W(π(y)|1), According to the relevant research of information theory, it can be known that the channel input that can reach the channel capacity of a symmetric discrete memoryless channel (DMC) is a uniform distribution on the input character set. which is Therefore, we also assume that the channel input is uniformly distributed in the following discussion. We construct a set of discrete memoryless channels The state transition function of is

Abstract

The embodiments of the invention relate to a polar code construction method and device, and network equipment. The method comprises the steps of: acquiring information to be transmitted; selecting atleast one polar channel from a plurality of polar channels for transmitting the information, wherein the at least one polar channel belongs to at least one channel sequence, and the channel capacitiesof any two polar channels included in each of the at least one channel sequence have a determined size relationship; and constructing a polar code for transmitting the information according to the number of the at least one polar channel. The method and the device can effectively reduce the complexity of polar code construction.

Description

technical field [0001] The present invention relates to the communication field, in particular to a polar code construction method, device and network equipment. Background technique [0002] Channel coding is one of the fundamental techniques in communication systems. Channel coding adds extra redundant bits to information bits, so that signal transmission can gain the ability to resist noise pollution. For a long time, channel coding has been one of the research focuses in communication circles. In recent years, a channel coding called polar code (Polar code) has rapidly attracted the attention of academic and industrial circles due to its excellent performance and low coding and decoding complexity. At the 87th meeting of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) Radio Access Network (RAN)1 held in November, polar codes were identified as enhanced mobile broadband (eMBB) ) control channel coding in the scenario. [0003] In the ...
