Index Coded PSK Modulation [PDF]
In this paper we consider noisy index coding problem over AWGN channel. We give an algorithm to map the index coded bits to appropriate sized PSK symbols such that for the given index code, in general, the receiver with large amount of side information ...

Design of a Labeling Scheme for 32-QAM Delayed Bit-Interleaved Coded Modulation [PDF]
It is very challenging to design the capacity-approaching labeling schemes for large constellations, such as 32-QAM, in delayed bit-interleaved coded modulation (DBICM).

Hard-Decision Coded Modulation for High-Throughput Short-Reach Optical Interconnect [PDF]
Coded modulation (CM), a combination of forward error correction (FEC) and high order modulation formats, has become a key part of modern optical communication systems.

Finite-Blocklength Analysis of Coded Modulation with Retransmission [PDF]
The rapid developments of 5G and B5G networks have posed higher demands on retransmission in certain scenarios. This article reviews classical finite-length coding performance prediction formulas and proposes rate prediction formulas for coded modulation

Multilevel Polar-Coded Modulation [PDF]
A framework is proposed that allows for a joint description and optimization of both binary polar coding and the multilevel coding (MLC) approach for $2^m$-ary digital pulse-amplitude modulation (PAM).

Layered HARQ Design for LDPC-Based Multi-Level Coded Modulation [PDF]
Multi-level coded modulation (MLCM) enhances data transmission by allocating error correction more effectively to bits with higher error probabilities, thus optimizing redundancy and improving performance.

Noncoherent coded modulation [PDF]
Summary: Trellis coded modulation with two or multidimensional signal constellations, together with coherent maximum-likelihood detection, is considered an attractive solution for communications over the additive white Gaussian noise (AWGN) channel. In this paper a new noncoherent communication system is introduced called noncoherent coded modulation ...

Improved Schemes of Differential Spatial Modulation
Differential spatial modulation (DSM) is able to transmit additional data bits without increasing the number of radio-frequency chains and power consumption and also avoids pilot overhead.

Optimized Modulation and Coding for Dual Modulated QR Codes
<p> We present optimized modulation and coding for the recently introduced dual modulated QR (DMQR) codes that extend traditional QR codes to carry additional secondary data in the orientation of elliptical dots that replace black modules in the barcode images. By dynamically adjusting the dot size, we realize gains in embedding strength for both
