Modeling and Performance of Aviation VHF Link Control (AVLC) Protocol for VDL Mode 2 System
2026 6th International Conference on Electronics, Circuits and Information Engineering (ECIE)To evaluate the performance of the Aviation VHF Link Control (AVLC) protocol in the VHF Data Link (VDL) Mode 2 system, a simulation model of the AVLC protocol was designed and implemented based on the Optimized Network Engineering Tools (OPNET).

VDL Mode E Receiver Performance Measurments
IEEE Aerospace and Electronic Systems Magazine, 2006VDL Mode E is a digital communications system proposed as a worldwide standard for replacement of the existing analog AM voice system used for VHF aeronautical communications. It provides a needed increase in voice channel capacity as well as offering a digital data link for CPDLC with the high integrity and low latency needed for time-critical ATC ...

Information search by applying VDL-based iconic tags: an experimental study
J. Documentation, 2019Purpose Visual Distinctive Language (VDL)-based iconic tags are structured visual information annotation. They explicate the content and organization of tagged information by graphical and symbolic features in order to improve the vocabulary problems of

VDL-based iconic co-annotation in crisis management
2014 International Conference on Collaboration Technologies and Systems (CTS), 2014Crisis management is typical collaborative work which requires multi types of actors to cooperate in decision making. Crisis Clever System (CCS) is a decision making environment based on emergency experience feedback and provides situation base for later cases.

Definition Einer Programmanalysemaschine in VDL
1978Bevor ein Programm optimiert werden kann, mus zur Ubersetzungszeit Information bestimmt und gesammelt werden. Die Techniken, die zur Bestimmung der Optimierungsinformation verwendet werden, gehen meist von der Darstellung des Programmes als Flusgraph aus [U 75, K 73, AC 76].

VDL—a Definition system for all levels
ACM SIGARCH Computer Architecture News, 1973The VDL system for the description of programming languages which was originally used for the definition of PL/I is extended to the description of processors. This paper shows the relationship between the language of definition and the abstract machine over which the semantics of the language are specified.

Linearly-arranged Concentric Circular Antenna Array Using Robust VDL technique
International Conference on Electrical Information and Communication Technologies, 2019The smart antenna has considered the most popular technologies in the modern communication system. Antenna array beamforming offers narrow beamwidth, low side-lobes, and high directivity. Termination of false signals and low sidelobe levels is a must for

Comparison of VDL modes in the aeronautical telecommunications network
Proceedings, IEEE Aerospace Conference, 2003VHF digital link (VDL) has been identified as a method of communication between aircraft and ground stations in the aeronautical telecommunications network (ATN). Three different modes of VDL have been suggested for implementation. Simulations were conducted to compare the data transfer capabilities of VDL modes 2, 3, and 4.

Semantically Structured VDL-Based Iconic Tags System
2013Iconic tags system based on Visual Distinctive Language has been developed and assessed improving tagging effectiveness by considering tagging quality and tagging speed. This amelioration benefits from semiotic interpretation of tag meaning and graphical code of tag structure.

A collisi on avoidance concept for VDL mode 2
2007 IEEE/AIAA 26th Digital Avionics Systems Conference, 2007The FAA is currently investigating the migration path to data-enabled digital air traffic services using VDL mode 2. Under certain loading conditions, simulations have shown that VDL mode 2 cannot meet future delay requirements with more than a few dozen aircraft per channel.
