Implementing the HanGÇôKobayashi Scheme Using Low Density Parity Check Codes Over Gaussian Interference Channels
2015 Edition, Volume 63, February 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We focus on Gaussian interference channels (GICs) and study the Han-Kobayashi coding strategy for the two-user case with the objective of designing implementable (explicit) channel codes. Specifically, low-density...

LDPC Code Design for Fading Interference Channels
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We focus on the two-user Gaussian interference channel (IC) with fading and study implementation of different encoding/decoding schemes with low-density parity-check (LDPC) codes for both quasi-static and fast fading...

Nonbinary multi-parallel-concatenated single-parity-check (NB-MPCSPC) codes over partial-response channels
2015 Edition, December 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we propose a high-rate nonbinary multi-parallel-concatenated single-parity-check (NB-MPCSPC) code as a low-complexity coding scheme for data storage channels. The proposed scheme is composed of parallel branches of...

Code Design for Discrete Memoryless Interference Channels
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We study design of explicit and implementable codes for the two-user discrete memoryless interference channels (DMICs). We consider Han-Kobayashi (HK) type encoding where both public and private messages are used, and propose coding techniques...

Universal Sparse Superposition Codes with Spatial Coupling and GAMP Decoding
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Sparse superposition codes, or sparse regression codes, constitute a new class of codes which was first introduced for communication over the additive white Gaussian noise (AWGN) channel. It has been shown that such codes are...

Analysis and design of Raptor codes using a multi-edge framework
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The focus of this paper is on the analysis and design of Raptor codes using a multi-edge framework. In this regard, we first represent Raptor codes as multi-edge type low-density parity-check (MET-LDPC) codes. This MET...

A user-independent serial interference cancellation based coding scheme for the unsourced random access Gaussian channel
2017 Edition, November 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We propose a novel coding scheme for the unsourced multiple access channel model introduced by Polyanskiy [1]. This new paradigm is composed of four main ingredients: (i) the transmission period is partitioned into sub-blocks, thereby instituting a slotted...

Improvements of quasi-cyclic low-density parity-check codes based on hybrid structures of BIBD's schemes
2012 Edition, December 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we propose a simple mathematical structure to improve the BER (bit error rate) performance of quasi-cyclic low-density parity-check (QC-LDPC) codes. Since the proposed structure can be defined in-between those of random codes...

Design Guidelines of Low-Density Parity-Check Codes for Magnetic Recording Systems
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

As one of the most classical data-storage systems, magnetic recording (MR) systems have attracted a significant amount of research attention in the past several decades due to the advantages of low cost and high storage density. Along with the continual...

Randomized Serially Concatenated LDGM Codes for the Gaussian Wiretap Channel
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We study application of a special class of low density parity check (LDPC) codes to the wiretap channel. Specifically, we construct a randomized coding scheme based on serially concatenated low density generator matrix...
