OSSIE Version 0.6.2 Available for Free Download
Wireless @ Virginia Tech is pleased to announce that OSSIE version 0.6.2 is available for free download at http://ossie.wireless.vt.edu.
OSSIE is an open source Software Defined Radio (SDR) development effort based at Virginia Tech. OSSIE is primarily intended to enable research and education in SDR and wireless communications. The software package includes an SDR core framework based on the JTRS Software Communications Architecture (SCA), tools for rapid development of SDR components and waveforms (applications), and an evolving library of pre-built components and waveforms. In addition, free laboratory exercises for SDR education and training are being developed in cooperation with the Naval Postgraduate School and are used in graduate SDR courses at both institutions.

Features of OSSIE 0.6.2
OSSIE 0.6.2 has been installed on PCs running Fedora Core 7 or 8 Linux, but can be ported to other Linux or Unix based operating systems.  Wireless @ Virginia Tech plans to release a version of OSSIE with enhanced support for embedded as well as PC based applications in the fall of 2008.

• Simplified installation
• ALF, a new waveform visualization and debugging tool, donated by SAIC, that includes
• capability to display components that make up a waveform, and their ports and connections
• plug-in tools for applying signals and monitoring response of components or waveforms
• capability to run individual components as stand-alone waveforms
• capability to connect a port on a component in one waveform to a port on a component in another waveform
• ability to monitor throughput of components developed with support for this feature
• An updated version of the OSSIE Waveform Developer (OWD) that includes support for developing Python components and for developing components with timing support for use with ALF
• The ability to save and reuse node configurations for multiple waveforms

Components for OSSIE 0.6.2

OSSIE 0.6.2 is supplied with a demonstration waveform that simulates a simple QPSK system. The components that make up the waveform can be used as a model for modifying existing OSSIE 0.6.1 components to work with OSSIE 0.6.2.  A Component Update Guide is also available.

Laboratory/tutorial exercises for OSSIE, developed in cooperation with the Naval Postgraduate School, are available, along with additional components, devices, and node configurations.
