TX and RX condition assessment for proposed FH automatic link
ALE is the acronym for Automatic Link Establishment. ALE is the de-facto worldwide standard for initiating and sustaining communications using High Frequency radio. HF radio conveys signals via ionospheric propagation, a constantly changing medium.

With an unrivalled pedigree in HF communications, Leonardo has developed Third Generation Automatic Link Establishment (3G ALE) algorithms that ensure that links are automatically established and maintained to achieve successful trafic transfer without operator intervention. HF2000 monitors link quality and selects the best transmission frequency.

(PDF) Automatic link establishment for HF radios
This paper examines existing automatic link establishment (ALE) techniques for high frequency (HF) radio systems, identifying areas of improvement in calling techniques and protocols for ALE. Automated HF radio systems improved in these areas have been implemented, and results of these implementations are presented. Compromises between link establishment time and reliability are also considered.

AUTOMATIC LINK ESTABLISHMENT Third-generation ALE (3G-ALE) is designed to quickly and efficiently establish one-to-one and one-to-many (both broadcast and multicast) links. It uses a specialized carrier-sense-multiple-access (CSMA) scheme to share calling channels, and monitors traffic channels prior to using them to avoid interference. Scanning

AUTOMATIC LINK ESTABLISHMENT 3.1 Introduction and overview of automatic link establishment systems The United States has developed a series of HF radio standards that characterize and specify protocols and parameters for automatic link establishment (ALE), networking, linking protection, high-speed data modems, and basic HF radio parameters.
PPT Automatic Link Establishment for Amateur Radio Status Report
Automatic link establishment (ALE) was developed to automatically select a frequency that will support automatic linking between stations in a network or point-to-point communication without operator assistance. This new technology has given HF radio a renewed sense of being.
Proposed waveform for automatic link establishment Download
Automatic Link Establishment ( ALE) is the principle where a specialized radio modem, known as an ALE adaptive controller, is assigned the task of automatically controlling an HF receiver and transmitter in order to establish the highest quality communication link with 1 or multiple HF radio stations.
General Dynamics upgrading Navy shipboard radio with longrange HF
Automatic Link Establishment (ALE) is crucial to channel assignment and data exchange in HF radio networks. The link establishment interval and quality are two main concerns in this context. In jamming environments, the jammer signals seriously influence the channel quality.
Automatic Link Establishment The Key to Reliable Helicopter NOE
Automatic Link Establishment (ALE) was developed to provide for establishing best quality high frequency communications without the need for consulting propagation forecast information, or the need of having training to interpret propagation forecast information.
