Full-Size Form Factor

Full-Size Form Factor

This environment emulates a military radio unit as could be used for high bandwidth, high performance requirement communications systems (e.g. satellite communications or networking) or for applications such as radar or signal intelligence (spectrum monitoring).

As depicted in Figure 4, the actual Software Defined Radio is a single unit shown in the blue box and would include the processing element and the RF transceiver section. The workstation provides the User Interface and is also used during the development cycle. Connectivity between the two is performed via Ethernet or USB port.

User Interface

The UI, developed in JAVA, will be running on the desktop workstation. The NordiaSoft Radio Manager application could be used or the client may develop its own UI interface using functionalities of the Radio Manager.   The audio card of the desktop (microphone and speaker) is to be used for audio-in and audio-out while the screen can be used for data presentation.


Signal Processing Unit and RF Transceiver Unit

For the Full-size Form Factor, the signal processing and RF transceiver functions will be provided within the same unit, on different cards. Connectivity between the cards will be done via a high-speed backplane. The SCA Domain Manager would reside in the SDR unit and the desktop computer would host a Device Manager for its I/O ports.

In this environment, the FPGA are much larger than in the previous two platform categories. In addition, the FPGA is user-programmable as opposed to being loaded at boot time. This important feature enables the user to modify the FPGA image without having to shut down and reboot the unit. The RF transceiver is also of higher quality and provides much higher data-handling rates. Those units also come with real-time operating systems such as Green Hills INTEGRITY or Wind River VxWorks. With their modular design, they also offer the advantage of being scalable enabling upgrades to newer material.


Development Environment

A desktop computer is needed for the development environment, in addition to providing the application UI functionalities. Note that those two functionalities can be executed on separate computer, it is proposed here to use the same for cost saving. The workstation would host the SCA Architect development tool, the programming development environment, the OS compiler and ORB libraries.
