    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate than 4G communication systems such as LTE systems. The disclosure relates to a method and device for dynamically selecting, or simultaneously performing, PAC code-based Fano decoding and/or list decoding in a wireless communication system. The method for performing PAC code-based decoding by a reception device in a wireless communication system comprises identifying a specific criterion variable related to a channel state for selecting at least one of Fano decoding or list decoding for a signal received from a transmission device, comparing the specific criterion variable related to the channel state with a threshold, performing the Fano decoding in case that the specific criterion variable related to the channel state satisfies the threshold, and performing the list decoding in case that the specific criterion variable related to the channel state does not satisfy the threshold.

    Abstract: Devices, systems and methods for list decoding of polarization-adjusted convolutional (PAC) codes are described. One example method for improving error correction in a decoder for data in a communication channel includes receiving a noisy codeword, the codeword having been generated using a polarization-adjusted convolutional (PAC) code and provided to the communication channel prior to reception by the decoder, and performing PAC list decoding on the noisy codeword, wherein an encoding operation of the PAC code comprises a convolutional precoding operation that generates one or more dynamically frozen bits, and wherein the PAC list decoding comprises extending, based on the one or more dynamically frozen bits, at least two paths of a plurality of paths in the PAC list decoding differently and independently.

    Abstract: Various implementations described herein relate to correcting errors in Dynamic Random Access Memory (DRAM). A memory controller uses an Error Correcting Code (ECC) to store an encoded data word within a DRAM die. The DRAM die is communicatively coupled the memory controller by a memory data bus. The DRAM die includes on-die error correction for data bits stored in the DRAM. Upon reading the encoded data word, the memory controller corrects and detects one or more errors. The one or more errors are introduced by at least one of the on-die error correction of the DRAM die or the memory data bus.

    Abstract: A method for determining the n best positions of frozen bits in a channel decoder for a noisy communication channel. A decoding method and decoding processing unit for implementing the channel having frozen bits at the n worst positions. A method and system that iteratively, for each bit i from the n bits, determines a probability vector for the bit i by traversing a logical graph using contraction identities simplified to specific values, indexes the specific values from the contraction identities newly computed during the determination of the probability vector for subsequent reference during a following iteration based on corresponding contraction identities, fixes the bit i from the probability vector and moving to bit i+1 until all n bits are fixed.

    Abstract: A wireless device generates a High Efficiency Signal B (HE-SIG-B) field by Block Convolution Code (BCC) encoding and rate-matching a BCC block of the HE-SIG-B field, generates a Physical Layer Protocol Data Unit (PPDU) including the HE-SIG-B field, and transmits the PPDU. A total number N is a total number of bits of the HE-SIG-B field that precede the BCC block, and is greater than 0. The BCC block has a puncturing pattern depending on the total number N. A wireless device receives a PPDU. The PPDU includes an HE-SIG-B field that includes an encoded BCC block. The wireless device de-rate-matches the encoded BCC block having a puncturing pattern depending on a total number N. The total number N is a total number of decoded bits of the HE-SIG-B field that preceded the BCC block, and the total number N is greater than 0.

    Abstract: A method for execution by one or more modules of one or more processors of a storage network includes receiving a data object for storage, segmenting the data object into a plurality of data segments and determining a level of security and a level of performance for the plurality of data segments. The method continues by determining whether one or more data segments of the plurality of data segments is to be transformed using an all-or-nothing transformation and in response to a determination to transform one or more data segments of the plurality of data segments, transforming a data segment of the plurality of data segments to produce a transformed data segment. The method continues by dispersed error encoding the transformed data segment to produce a set of encoded data slices and transmitting the set of encoded data slices to a set of storage units of the storage network.

    Abstract: An encoder receives a concatenated encoder input block d, splits d into an outer code input array a, and encodes a using outer codes to generate an outer code output array b. The encoder generates, from b, a concatenated code output array x using a layered polarization adjusted convolutional (LPAC) code. A decoder counts layers and carries out an inner decoding operation for a layered polarization adjusted convolutional (LPAC) code to generate an inner decoder decision {tilde over (b)}i from a concatenated decoder input array y and a cumulative decision feedback ({circumflex over (b)}1, {circumflex over (b)}2, . . . , {circumflex over (b)}i−1). The decoder carries out an outer decoding operation to generate from {tilde over (b)}i an outer decoder decision âi, and carries out a reencoding operation to generate a decision feedback {circumflex over (b)}i from âi, where the number of layers is an integer greater than one, with a concatenated decoder output block {circumflex over (d)} being generated from outer decoder decisions.
