Web15 de fev. de 2024 · List Viterbi Decoding of PAC Codes Abstract: Polarization-adjusted convolutional (PAC) codes are special concatenated codes in which we employ a one-to-one convolutional transform as a pre-coding step before the polar transform. WebReduction of Polar Codes and PAC Codes Mohsen Moradi , Amir Mozammel Abstract—Sorting operation is one of the main bottlenecks for the successive-cancellation list (SCL) decoding. This paper introduces an improvement to the SCL decoding for polar and pre-transformed polar codes that reduces the number of

Web1 de mar. de 2024 · The remainder of this paper is organized as follows: Section 2 provides a background on PAC codes and list decoding. Section 3 introduces the proposed fast list decoders for PAC codes. Simulation results are provided in Section 4. Finally, Section 5 draws the main conclusions of the paper. 2 BACKGROUND PAC codes. The PAC … WebWe also prove that the upper bound of the PAC codes computation has a Pareto distribution; our simulation results also verify this. Furthermore, we present a scaling-bias procedure and a method of choosing threshold spacing for the search-limited sequential decoding that substantially improves the decoders average computation.

Web20 de jul. de 2024 · Polar codes are the first class of channel codes achieving the symmetric capacity of the binary-input discrete memoryless channels (B-DMC) with efficient encoding and decoding algorithms. But the weight spectrum of polar codes is relatively poor compared to Reed-Muller (RM) codes, which degrades their maximum-likehood … Webcodes, then we focus on PAC codes. A. Polar Codes and List Decoding A polar code of length N = 2n with K information bits is denoted by P(N,K,A), where Ais the data index set. The information bits d of length K is embedded in the vector u such that uA = d, and uAc = 0 which are called frozen bits. The set Aconstitutes of indices of reliable sub ...
