Scaling Analysis of Multilevel Polar Coded Modulation

open access: yesIEEE Access, 2019
In this paper, we analyze and prove the capacity-achieving property of the equivalent asymmetric channels of multilevel polar-coded modulation in view of the scaling assuming regime, which employ some techniques of symmetric channels.

LDPC-Coded Modulation Performance Analysis and System Design

open access: yesIEEE Access, 2020
In this work, the low-density parity-check (LDPC)-coded modulation scheme which has been selected for inclusion in the next generation of International Telecommunication Union (ITU) broadband standard is investigated.

Improving the performance of BICM-ID and MLC systems with different FEC codes [PDF]

open access: yesAdvances in Radio Science, 2013
In bandwidth limited communication systems, the high data rate transmission with performance close to capacity limits is achieved by applying multilevel modulation schemes in association with powerful forward error correction (FEC) coding, i.e.

Iterative Polar Quantization-Based Modulation to Achieve Channel Capacity in Ultrahigh-Speed Optical Communication Systems

open access: yesIEEE Photonics Journal, 2010
In this paper, we propose a nonuniform coded-modulation format based on iterative polar quantization (IPQ) as a scheme to enable achieving channel capacity in ultrahigh-speed optical communication systems.

Hybrid neural coded modulation: Design and training methods

open access: yesICT Express, 2022
We propose a hybrid coded modulation scheme which composes of inner and outer codes. The outer-code can be any standard binary linear code with efficient soft decoding capability (e.g. low-density parity-check (LDPC) codes).

Multinary-Signaling-Based Coded Modulation for Ultrahigh-Speed Optical Transport

open access: yesIEEE Photonics Journal, 2015
A multinary-signaling-based coded-modulation (CM) scheme is proposed, which is suitable for various applications ranging from multi-Tb/s to multi-Pb/s data rates, outperforming conventional CM schemes in terms of both spectral and energy efficiencies ...

Bit-Permuted Coded Modulation for Polar Codes [PDF]

open access: yes2017 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2017
We consider the problem of using polar codes with higher order modulation over AWGN channels. Unlike prior work, we focus on using modulation independent polar codes. That is, the polar codes are not re-designed based on the modulation used. Instead, we propose bit-permuted coded modulation (BPCM): a technique for using the multilevel coding (MLC ...

A Note on the Dual Codes of Module Skew Codes [PDF]

open access: yes, 2011
In [4], starting from an automorphism θ of a finite field ${\mathbb F}_q$ and a skew polynomial ring $R={\mathbb F}_q[X;\theta]$ , module θ -codes are defined as left R -submodules of R /Rf where f ∈R . In [4] it is conjectured that an Euclidean self-dual module θ -code is a θ -constacyclic code and a proof is given in the special ...

Probabilistic Shaping Design Based on Reduced-Exponentiation Subset Indexing and Honeycomb-Structured Constellation Optimization for 5G Fronthaul Network

open access: yesIEEE Access, 2019
A probabilistic shaping method based on reduced-exponentiation subset indexing and honeycomb-structured constellation optimization is proposed to compress the number of signal points in the constellation, so that the total number doesn't fit the ...
