Link 11 Tactical Chain of Command Simulation System
The Link11 Tactical Chain of Command Simulation System is based on
the open source software GNURadio and MATLAB designed to operate
flawlessly on all models of the SDR-LW series of all-in-ones. It
mainly implements a series of simulations based on the Link11
transmission protocol, including simple Link11 signal coding
modulation, decoding after receiving through the wireless air
interface; radio silent mode of the slave; and polling call mode
based on configurable time window and number of devices for the
master and slave.
The main operating environment of this simulation software system
is:
1. Ubuntu operating system 18.04+
2, UHD 4.0+
3, MATLAB 2021a
4, GNURadio 3.9.2
The simulation system is divided into three modules (as shown in
the figure above), and when performing Link11 simulations, only two
RF channels of the SDR device are required, one for one receive and
one for transmission.
This experimental process fully simulates the Link11 protocol,
which can carry out the same frequency time division communication,
or the frequency division time division combination communication
(RF parameters can be configured at any time), and establish the
master station and slave networking through wireless communication.
This simulation system can complete practical exercises, simulation
verification and other teaching activities. At the same time, the
simulation system has the characteristics of sustainable
optimization and open source of the software platform. The
corresponding functions can be adjusted according to the needs of
actual simulation teaching and research.
