An Improved Blind Recognition Method for Synchronization Position and Coding Parameters of k/n Rate Convolutional Codes in a Noisy Environment

open access: yesIEEE Access, 2020
In digital communication systems, error correction codes are used to recover data that has been disturbed in a noisy environment. Convolutional code is a commonly used error correction code. In non-cooperative communication systems, it is very meaningful

A Serial Concatenation of Binary-Input Nonbinary-Output Convolutional Code and Recursive Convolutional Lattice Code

open access: yesIEEE Access, 2018
The recently proposed recursive convolutional lattice code (RCLC) can form a signal with pseudo-Gaussian constellations, and their parallel concatenation is shown to approach the Shannon limit.

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.
