Accurate Performance Analysis of Coded Large-Scale Multiuser MIMO Systems with MMSE Receivers

open access: yesSensors, 2019
In this paper, we estimate the uplink performance of large-scale multi-user multiple-input multiple-output (MIMO) networks. By applying minimum-mean-square-error (MMSE) detection, a novel statistical distribution of the signal-to-interference-plus-noise ...

An efficient algorithm for the reconstruction of punctured convolutional codes

open access: yesEURASIP Journal on Wireless Communications and Networking, 2017
Puncturing is one of the methods of increasing the code rate, and the original code before puncturing is called the mother code. Any (N,K) convolutional code is obtainable by puncturing some (n,1) mother codes.

A new approach to software vulnerability detection based on CPG analysis

open access: yesCogent Engineering, 2023
Detecting source code vulnerabilities is an essential issue today. In this paper, to improve the efficiency of detecting vulnerabilities in software written in C/C++, we propose to use a combination of Deep Graph Convolutional Neural Network (DGCNN) and ...

Private Streaming With Convolutional Codes [PDF]

open access: yesIEEE Transactions on Information Theory, 2018
Recently, information-theoretic private information retrieval (PIR) from coded storage systems has gained a lot of attention, and a general star product PIR scheme was proposed. In this paper, the star product scheme is adopted, with appropriate modifications, to the case of private (e.g., video) streaming.

Generalized Weights of Convolutional Codes

open access: yesIEEE Transactions on Information Theory, 2023
In 1997 Rosenthal and York defined generalized Hamming weights for convolutional codes, by regarding a convolutional code as an infinite dimensional linear code endowed with the Hamming metric. In this paper, we propose a new definition of generalized weights of convolutional codes, that takes into account the underlying module structure of the code ...

Space-Time Convolutional Codes over Finite Fields and Rings for Systems with Large Diversity Order

open access: yesEURASIP Journal on Wireless Communications and Networking, 2008
We propose a convolutional encoder over the finite ring of integers modulo pk,ℤpk, where p is a prime number and k is any positive integer, to generate a space-time convolutional code (STCC).
