Serially Concatenated Polar Codes
IEEE Access, 2018 Simulation results show that the performance of polar codes is improved vastly by using polar codes as inner codes in serially concatenated coding schemes.

BER Evaluation Based SCFlip Algorithm for Polar Codes Decoding
IEEE Access, 2020 Successive cancellation (SC) decoding of polar codes may bring about error propagation that needs to be mitigated. In this paper, we present a new SC Flipping (SCFlip) decoder, named bit error rate (BER) evaluation based SCFlip (BER-SCFlip), which can ...

Alluvial ridge morphology on avulsing rivers
Sedimentology, EarlyView.ABSTRACT Alluvial ridges are built by preferential channel‐belt deposition and control river avulsions, yet a systematic analysis of their morphology has been missing. To address this gap, we analyse a globally distributed dataset of 8970 alluvial ridge flanks on 14 different rivers.

A Deep Learning Model of Lightning Stroke Density
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.Abstract Lightning plays a crucial role in the Earth's climate system; however, existing parameterizations for use in forecasting and earth system models show room for improvement in capturing spatial and temporal variations in its frequency. This study develops deep learning‐based parameterizations of lightning stroke density using meteorological ...

A Flip-Syndrome-List Polar Decoder Architecture for Ultra-Low-Latency Communications
IEEE Access, 2019 We consider practical hardware implementation of polar decoders. To reduce latency due to the serial nature of successive cancellation, existing optimizations improve parallelism with two approaches, i.e., multi-bit decision or reduced path splitting. In

Fast Simplified Successive-Cancellation List Decoding of Polar Codes [PDF]
2017 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2017 Polar codes are capacity achieving error correcting codes that can be decoded through the successive-cancellation algorithm. To improve its error-correction performance, a list-based version called successive-cancellation list (SCL) has been proposed in the past, that however substantially increases the number of time-steps in the decoding process. The
