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

open access: yesIEEE 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 (

Achieving the Uniform Rate Region of General Multiple Access Channels by Polar Coding [PDF]

open access: yes, 2016
We consider the problem of polar coding for transmission over $m$-user multiple access channels. In the proposed scheme, all users encode their messages using a polar encoder, while a multi-user successive cancellation decoder is deployed at the receiver.

Multi-CRC Polar Codes and M-SCFlip-Based Decoding

open access: yesIEEE Access, 2019
A multi-cyclic redundancy check (Multi-CRC) polar code construction algorithm is proposed in this paper to solve the error propagation problem of successive cancellation decoding for polar codes.

Polar Code Construction for BP Decoder

open access: yesIEEE Communications Letters, 2019
Belief propagation (BP) is a high-throughput decoding algorithm for polar codes, but the performance under BP decoder is not satisfactory due to the mismatch between the virtual channels seen by the BP decoder and bit-channel in the conventional construction method.

Nonbinary polar coding with low decoding latency and complexity

open access: yesJournal of Information and Intelligence, 2023
In this paper, we propose a new class of nonbinary polar codes, where the symbol-level polarization is achieved by using a 2 × 2 q-ary matrix 10β1 as the kernel.

Polar Codes for the m-User MAC [PDF]

open access: yes, 2010
In this paper, polar codes for the $m$-user multiple access channel (MAC) with binary inputs are constructed. It is shown that Ar{\i}kan's polarization technique applied individually to each user transforms independent uses of a $m$-user binary input MAC

Reinforcement Learning for Nested Polar Code Construction [PDF]

open access: yes2019 IEEE Global Communications Conference (GLOBECOM), 2019
In this paper, we model nested polar code construction as a Markov decision process (MDP), and tackle it with advanced reinforcement learning (RL) techniques. First, an MDP environment with state, action, and reward is defined in the context of polar coding. Specifically, a state represents the construction of an $(N,K)$ polar code, an action specifies

Rewriting Flash Memories by Message Passing [PDF]

open access: yes, 2015
This paper constructs WOM codes that combine rewriting and error correction for mitigating the reliability and the endurance problems in flash memory. We consider a rewriting model that is of practical interest to flash applications where only the second
