Software Communications Architecture Reference Implementation
The Software Communications Architecture Reference Implementation (SCARI) is an implementation of the US Military's Joint Tactical Radio System (JTRS) Software Communications Architecture (SCA) Core Framework. It was developed mainly by the Canadian Communications Research Centre (CRC) under contract by the Software Defined Radio Forum (now Wireless Innovation Forum). The code is openly available, as well as the full documentation, which is extensively cross-referenced with the original SCA specification documents. History The initial release of SCARI was based on version 2.1 of the SCA (released in mid-2001). This first release was developed by the CRC in collaboration with Defence Research and Development Canada (DRDC). In 2004 the SDR Forum contracted Canada's CRC one more time, in order to upgrade the SCARI to version 2.2 of the SCA (released in late 2001). This time CRC collaborated with three private companies and two US Government entities: *ISR Technologies (Canada), *Mer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Communications Architecture
The Software Communications Architecture (SCA) is an open architecture Open architecture is a type of computer architecture or software architecture intended to make adding, upgrading, and swapping components with other computers easy. For example, the IBM PC, Amiga 2000 and Apple IIe have an open architecture supp ... framework that defines a standard way for radios to instantiate, configure, and manage waveform applications running on their platform. The SCA separates waveform software from the underlying hardware platform, facilitating waveform software portability and re-use to avoid costs of redeveloping waveforms. The latest version is SCA 4.1. Overview The SCA is published by the Joint Tactical Networking Center (JTNC). This architecture was developed to assist in the development of Software Defined Radio (SDR) communication systems, capturing the benefits of recent technology advances which are expected to greatly enhance interoperability of communication systems an ...

Wireless Innovation Forum
Established in 1996, the Wireless Innovation Forum is a non-profit " mutual benefit corporation" dedicated to advocating for spectrum innovation and advancing radio technologies that support essential or critical communications worldwide. Forum members bring a broad base of experience in Software Defined Radio, Cognitive Radio and Dynamic Spectrum Access technologies in diverse markets and at all levels of the wireless value chain to address emerging wireless communications requirements. The forum acts as a venue for its members to collaborate to achieve these objectives. History The Wireless Innovation Forum was founded in 1996 originally as "The Modular Multifunction Information Transfer System Forum". The organization was created at the request of the US military services (led by the Air Force) as an industry association focused on advancing the development of software radio. In 1996, the Forum formed the Mobile Working Group to develop software specifications and standards ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defence Research And Development Canada
Defence Research and Development Canada (DRDC; , ''RDDC'') is the science and technology organization of the Department of National Defence (Canada), Department of National Defence (DND), whose purpose is to provide the Canadian Armed Forces (CAF), other government departments, and public safety and national security communities with military science, knowledge and military technology, technology. DRDC has approximately 1,400 employees across seven research centres within Canada. History After the First World War, national research and development in Canada was organized under the National Research Council (Canada), National Research Council (NRC). The NRC was founded in 1925 based on a wartime British recommendation to establish military laboratories in Canada, but by that time the main priorities were developing domestic university and industrial research and civilian projects.Turner, p. 15 Greater interest in military applied research arrived in 1935Turner, p. 16 when Major- ...

Joint Tactical Radio System
The Joint Tactical Radio System (JTRS) aimed to replace existing radios in the American military with a single set of software-defined radios that could have new frequencies and modes (“waveforms”) added via upload, instead of requiring multiple radio types in ground vehicles, and using circuit board swaps in order to upgrade. JTRS has seen cost overruns and full program restructurings, along with cancellation of some parts of the program. JTRS HMS (Handheld, Manpack & Small Form-Fit (SFF)) radios are jointly developed and manufactured by Thales and General Dynamics Mission Systems. These software-defined radios are designed as successors to the JTRS-compatible CSCHR (Consolidated Single Channel Handheld Radios, ie. AN/PRC-148 and AN/PRC-152), securely transmitting voice and data simultaneously using Type 2 cryptography and the new Soldier Radio Waveform. The Army announced in June 2015 a Request for Proposal (RFP) for full-rate production of the HMS program. Goal wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Java Programming Language
Java is a high-level, general-purpose, memory-safe, object-oriented programming language. It is intended to let programmers ''write once, run anywhere'' ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. Java gained popularity shortly after its release, and has been a popular programming language since then. Java was the third most popular programming language in according to GitHub. Although still widely popular, there has been a gradual decline in use of Java in recent years with other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
