DNN assisted Sphere Decoder
2019 Edition, July 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A modified sphere decoding (SD) scheme is proposed for multiple-input multiple-output (MIMO) communication systems in this paper. The contribution of the paper includes the introduction of a systematic approach to sphere radius design and control...

Enabling Sphere Decoding for SCMA
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we propose a reduced-complexity optimal modified sphere decoding (MSD) detection scheme for SCMA. As SCMA systems are characterized by a number of resource elements (REs) that are less than the number of the supported users, the...

Generalized Sphere Packing Bound
2015 Edition, Volume 61, May 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Kulkarni and Kiyavash recently introduced a new method to establish upper bounds on the size of deletion-correcting codes. This method is based upon tools from hypergraph theory. The deletion channel is represented by a hypergraph whose edges are the deletion...

Surface Layer Analysis of a²⁸Si-Enriched Sphere Both in Vacuum and in Air by Ellipsometry
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

For a new definition of the kilogram, surface analysis of Si spheres is essential to determine the Avogadro constant using the X-ray crystal density method. In this paper, to investigate the surface characteristics of Si spheres both in...

Surface Layer Analysis of Si Sphere by XRF and XPS
2015 Edition, Volume 64, June 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

To reduce the uncertainty of the Avogadro constant for the new definition of the kilogram, the surface analysis of the Si sphere produced for the accurate determination of the Avogadro constant is indispensable. In this paper, we conducted the...

Magnetohydrodynamics simulation in a sphere by Yin-Yang-Zhong grid
2016 Edition, July 1, 2016 - Southern California Institute of Technology

For numerical simulations in a sphere, we have recently proposed a new spherical grid system called Yin-Yang-Zhong grid. The Yin-Yang-Zhong grid is composed of three components - Yin, Yang, and Zhong - that are combined to cover a spherical region...

A new ordering for efficient sphere decoding
2005 Edition, Volume 3, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a novel pre-processing stage that offers significant improvement in the computational efficiency of sphere decoding by imposing a geometrically-inspired ordering on the columns of the channel matrix. By studying the...

Surface layer analysis of Si sphere by XRF and XPS
2014 Edition, August 1, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

To reduce the uncertainty of the Avogadro constant for the new definition of the kilogram, the surface analysis of the Si sphere produced for the accurate determination of the Avogadro constant is indispensable. In this work, we conducted the surface...

Reduced complexity Sphere Decoding
2011 Edition, July 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In Multiple-Input Multiple-Output (MIMO) systems, Sphere Decoding (SD) can achieve performance equivalent to full search Maximum Likelihood (ML) decoding with reduced complexity. Several researchers reported techniques that reduce the complexity of SD further. In this...
