Arikan polar codes
WebPolar coding, recently invented by Erdal Arıkan, is an encoding/decoding scheme that provably achieves the capacity of the class of symmetric binary memoryless channels. In this thesis, we address two important problems regarding polar codes: the construction of polar codes and performance of polar codes. First, we consider the problem of ... WebThe key code is in class PolarCode (C and MATLAB). The interface to this class is as follows: constructor Input: N or n, K, epsilon, CRC Output: None Function: create polar …

WebAs noted by Arikan shortly after the invention of polar codes, their performance could be improved dramatically if we had a genie that intervenes in the successive cancellation decoding process only a few times to reverse incorrect decisions on information bits. Web21 lug 2009 · Abstract: Polar coding, proposed by Arikan, makes it possible to construct capacity-achieving codes for symmetric binary-input discrete memoryless channels, with low encoding and decoding complexity. Complexity of the originally proposed code construction method, however, grows exponentially in the blocklength unless a channel …

Web11 apr 2024 · Polar Code的优势 Polar码：即极化码。与有着50多岁高龄的LDPC码相比，Polar码完全算得上少年儿童。Polar码由土耳其教授Erdal Arikan在2008年提出。Polar码基于信道极化理论，在解码时将信道分为无噪信道和全噪信道，将有用的信息分到无噪信道，将垃圾信息分到全噪信道。 Web21 mag 2024 · The polar codes are constructed at a fixed design-SNR equals to zero using Arikan’s Bhattacharyya bounds that is also explained in detail in . BPSK modulation is then used, followed by optimal power allocation and orthonormal transformation as explained before in the previous section, and finally a guard period of length L is appended to the …
