A Flexible Polar Decoding Architecture With Adjustable Latency and Reliability

IEEE Open Journal of the Communications Society
Future mobile and wireless communications should support various applications with their own reliability and latency requirements. Polar codes, adopted in the 5G standard, are capacity achieving as the codeword length increases even with low complexity ...

Concatenated LDPC-Polar Codes Decoding Through Belief Propagation

, 2017
Owing to their capacity-achieving performance and low encoding and decoding complexity, polar codes have drawn much research interests recently. Successive cancellation decoding (SCD) and belief propagation decoding (BPD) are two common approaches for ...

Are Workplace Friendships Nothing for Older Workers? Decoding the Psychological Mechanisms Linking Age to Workplace Friendship

Journal of Organizational Behavior, EarlyView.
ABSTRACT Given the benefits of workplace friendship, understanding its maintenance is essential. Age is particularly relevant due to the aging and increasingly age‐diverse workforce, yet its relationship with workplace friendship remains unclear, with prior studies reporting positive, negative, or null correlations. As age itself is a proxy for further

Low-Complexity CRC Aided Joint Iterative Detection and SCL Decoding Receiver of Polar Coded SCMA System

IEEE Access, 2020
As the fifth-generation (5G) wireless networks' key technology, the joint design of SCMA and polar code is concerned by the future communication system. In this paper, a CRC aided joint iterative detection and successive cancellation list (SCL) decoding (

Partial Sums Generation Architecture for Successive Cancellation Decoding of Polar Codes

, 2013
Polar codes are a new family of error correction codes for which efficient hardware architectures have to be defined for the encoder and the decoder. Polar codes are decoded using the successive cancellation decoding algorithm that includes partial sums ...

Multiple Folding for Successive Cancelation Decoding of Polar Codes

IEEE Wireless Communications Letters, 2014
Polar coding is known as the first provably capacity-achieving coding scheme under low-complexity suboptimal successive cancelation decoding (SCD). The large error-correction capability of finite-length polar codes is mostly achieved with relatively long codes.

Mode Integration Disorder Metamaterials: Electromagnetic Wave Manipulation From Arbitrary Coupled Modes to Single Mode

Laser &Photonics Reviews, EarlyView.
When a uniform field interacts with a complex medium, it becomes scattered into a nonuniform distribution. A mode‐integration metamaterial employs its intrinsic controlled disorder to coherently reorganize and integrate the scattered field components into a tailored modal output, establishing a new paradigm for programmable modal coupling and versatile

Velocity Spectrum Imaging Using Velocity Encoding Preparation Pulses

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The goal of this article is to introduce a technique to measure the velocity distribution of water inside each voxel of an MR image. The method is based on the use of motion sensitizing gradients with changing first moment to encode velocity. As such, it is completely non‐invasive and requires no contrast injections.

Pole‐To‐Pole 3D Radial Trajectory Designs Improve Image Quality and Quantitative Parametric Mapping in the Brain and Heart

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To design 3D radial spiral phyllotaxis trajectories aimed at removing phase inconsistencies, improving image quality, and enhancing parametric mapping accuracy by acquiring nearly opposing spokes starting from both hemispheres in 3D radial k‐space. Methods Two 3D radial trajectories, pole‐to‐pole and continuous spiral phyllotaxis, were
