Details
Today high-frequency (HF) radio data communications technology is more relevant than ever, continually advancing with fourth-generation systems currently being deployed. Advances in digital signal processor technology, together with the need to confront vulnerabilities and shortcomings in legacy architectures, demand for a rethink of future-looking HF systems at all levels of the communication layer model.
This tutorial will present benefits to Australian Defence through extensions to current as well as new architectures, relevant to HF communications systems, considering both data and digital voice traffic. Utilization of both legacy bulk serial cryptography as well as modern IP-based encryptors are presented. Modern NATO architectures will be explored together with latest editions of interoperability standards. Architecture for using STANAG 5066 both as a Red-side and Black-side ARQ protocol are considered including standard use and resilient extensions to both MIL-STD-188-110D wideband waveforms and MIL-STD-188-141D (4G) link establishment.
Importantly, IP services over HF are recognized as a crucial future requirement. Architecture to achieve this is presented for STANAG 4691 (MARLIN) and new packet-based wideband (WB-RDL) waveforms, both in standard and resilient modes.
