Link-11 communications

Abstract

This thesis provides the reader with an overview of the Link-11 system and what telecommunication assets are needed to operate the system. Fundamental aspects of High Frequency (HF), Ultra High Frequency (UHF), and communication configurations are reviewed. An examination of the Link-11 equipment operations is presented. This includes a description of the Tactical Data Set (TDS) computer and encryption device. The thesis also contains an in-depth review of the Data Terminal Set (DTS). The specific operations of the DTS that are studied are Error Detection and Correction (EDAC), audio signal generation, link protocol control, NTDS computer interface, and digital/analog conversion. Distinctive Link-11 communication features are discussed. The features consist of Phase Shift Keying (PSK), signal generation, signal structure, and binary encoding. The protocol, consisting of frame structure, control codes, and net operation, which operates the net automatically is introduced. a review of radio equipment and its management concludes the thesis.
