The invention discloses a software communication system structure of a dual-core framework, including upper management software, an adaptation layer module and two core frameworks, the core frameworkcomprises a domain manager and a device manager. the adaptation layer module performs the following steps: 1, when the software communication architecture is initialized, the adaptation layer module causes the domain managers and the device managers in the two core frameworks to have the same attributes, and judges the master-standby relationship of the two core frameworks according to the defaultconditions; 2. In that run process of the software communication architecture, when the adaptation layer module receives the application instruction installation, the application uninstallation instruction and device registration instruction of the upper layer management software, the corresponding operation is completed by calling the operation interface in the main core framework through the CORBA middleware, the domain manager in the backup core framework and the attributes of the device manager are updated, and the device logout result is returned to the upper management software. Thirdly, when the adaptation layer module receives the feedback result of the domain manager or device manager failure of the main core framework, the backup core framework is enabled.

A software-defined GPS receiver includes a hardware-oriented front end for down converting and digitizing the signals received from GPS satellites. The GPS signal processing functions, such as acquisition / tracking and navigation computing, can be performed by software running on the receiver central processing unit (CPU), rather than by firmware in a custom hardware device such as an ASIC. The signal processing capabilities of the receiver can therefore be readily reconfigured (e.g., upgraded) to accommodate changes in the satellite signal transmissions. Moreover, by utilizing an operating environment architecture and application programs that are compliant with the Software Communications Architecture (SCA) specification, a distributed positioning system of scalable, portable, and compatible SCA-compliant software-defined GPS receivers can be realized.

A software-defined radio includes a pair of radio subsystems such as a red (command) and black (data) radio subsystem having an operating environment conforming to the Software Communications Architecture (SCA) specification, for example, as used for Joint Tactical Radio System (JTRS). A clock is read by at least one of the radio subsystems for determining time of day. A processor of the radio subsystem is operative for distributing the time of day to the radio subsystems using a global hardware timing pulse. Each processor can include a free-running timer to which any time sources within the pair of radio subsystems are set.

A Software Communications Architecture (SCA)-based software-defined radio (SDR) terminal and a reconfiguration method thereof are provided. The SDR terminal includes a software module including first and second hardware modules that are programmable and a memory storing at least one wireless access application; and a software module including a reconfiguration core framework that perform a service mode switch using the wireless access application, wherein, if a service mode switch from a first service mode to a second service mode occurs, the SDR terminal installs a wireless access application corresponding to the second service mode in one of the first and second hardware modules.

The invention discloses a method for actively registering components based on a software communication architecture. The method for actively registering the components provided by the invention has the advantages that a proxy design pattern is adopted, and component registry is completed by means of creating a component registry interface instance, so that the problem of bidirectional dependence between to-be-registered components and received registered components is effectively solved, therefore the software security is improved.

A software defined radio includes a radio circuit powered by a battery and formed as a pair of radio subsystems having radio components that draw power from the battery. An executable radio software system conforms to the Software Communications Architecture (SCA) specification and defines an operating platform environment that allows a waveform application to operate with the radio circuit. A power management service is operative with the pair of radio subsystems to coordinate the power among the radio components.

A software defined radio includes a radio circuit and an executable radio software system operable with the radio circuit and conforming to the software communications architecture (SCA) specification. An operating environment is defined and includes a plurality of waveform components that are loaded when the radio circuit is initialized or a waveform component is instantiated, and reloaded at runtime after the waveform component is instantiated for transmitting and receiving voice data.

A preparser tool is provided for converting Software Communications Architecture (SCA) Extensible Markup Language (XML) files into Common Object Request Broker Architecture (CORBA) structures usable by an SCA Core Framework (CF) and comprises a CF_PreParsers interface definition language (IDL) and a first preparser. The CF_IDL is configured to be in operable communication with an XML parser and with at least a first type of preparser. The first type of preparser is in operable communication with the CF_PreParsers IDL, is associated with a first type of descriptor for the CF, and is configured to call the XML parser to request parsing of a first set of first XML files, convert the first parsed set of first XML files into a first CORBA structure type, encode the first CORBA structure type into a first CORBA Common Data Representation (CDR) file; and write the first CORBA CDR file as a first octet sequence.

A software-defined radio includes an executable radio software system operable with a radio circuit and conforming to the software communications architecture (SCA) specification and defining an operating environment that allows a waveform application to operate with a radio circuit for transmitting and receiving voice and data. An extensible Human-Machine Interface (HMI) plugin module is operable for allowing a selected waveform application to integrate with the radio circuit and provide an HMI user interface.

A software communication architecture (SCA)-based system includes a plurality of components and a relay component connected to the plurality of components. Since data among the components are transmitted through the relay component, it is possible to reduce the complexity of connection caused by an increase in the number of components and to prevent a file size from increasing. Therefore, it is possible to reduce the parsing time of a domain profile and to reduce mode exchange time so that it is possible to rapidly perform connection setups in an embedded environment and to effectively perform communication.

A preparsers tool is provided for converting Software Communications Architecture (SCA) Extensible Markup Language (XML) files into Common Object Request Broker Architect (CORBA) structures usable by a Software Communications Architect (SCA) Core Framework (CF). The preparsers tool retrieves a set of target environment implementation definitions (TEID) that define at least one characteristic of a target environment to which a CORBA Common Data Representation (CDR) file is provided. For each component in the target environment, one or more dependencies are merged into an implementation device dependencies list that comprises visible device dependencies and external device dependencies. The parsed set of XML files is converted into a CORBA structure type, the conversion based at least in part on the TEID, such that the conversion of the parsed set of XML files results in a CORBA structure having a type and precedence order that is correct for the target environment.
