Spectrum Signal Processing Launches MILCOM Platform For International Markets

LONDON, UNITED KINGDOM--(CCNMatthews - Sept. 13, 2005) - Spectrum Signal Processing Inc. (TSX:SSY)(NASDAQ:SSPI) announced today at the Defense Systems and Equipment International tradeshow the launch of the flexComm™ SDR-3002 IMRDP, an international version of its existing military communications (MILCOM) rapid-prototyping development platform. This is the industry's first "RF to Ethernet" commercial-off-the-shelf (COTS) solution specifically targeting international MILCOM programs. This Software Communications Architecture (SCA) enabled platform integrates Spectrum's SDR-3002 with the new DRT4001 Software Defined Radio (SDR) Family of RF front-ends from Digital Receiver Technology, Inc. (DRT).

The SDR-3002 IMRDP is a turnkey black-side processing system for tactical military communications programs for the international community. This system includes sample application software supporting wide band frequency operation, making the SDR-3002 IMRDP ideal for rapid prototyping as well as both wide and narrowband waveform development. Additional benefits and features of this platform can be found at: www.spectrumsignal.com/products.

"Our exportable COTS SCA-enabled platform serves software defined radio development markets outside of North America," said Dan Simard, Managing Director of Spectrum Signal Processing (UK) Limited. "Governments and defense contractors worldwide have been studying and developing SDR technology for years and now have a proven platform on which to advance their programs. The SDR-3002 IMRDP provides a comprehensive solution that reduces developers' risk and time to deployment by providing integrated hardware, software, development tools, training and support."

The combination of the DRT4001 SDR Family of wide band digital RF subsystems with Spectrum's IF and baseband technology provides a scalable solution that should appeal to international waveform developers and others developing multi-channel applications.

Governments worldwide are adopting the SCA, which was developed under the auspices of the US Joint Tactical Radio Systems Joint Program Office. The SCA provides a core framework to enhance portability of military waveforms across disparate radio architectures. Software defined radios will be multi-mode and multi-band allowing one radio to communicate with diverse radio networks, typical of international coalition forces. It allows over-the-air reprogramming of those radio sets to enable the information superiority necessary for more effective military engagements.

The SDR-3002 IMRDP system is comprised of Spectrum's SDR-3002 software defined radio processing and analog-to-digital converter/digital-to-analog converter boards (PRO-3100, PRO-3500 and TM1-3350) in a four slot 2U CompactPCI® chassis. The system includes all software application libraries, including digital down-conversion and digital up-conversion field programmable gate array cores, operating systems and an SCA core framework. A working software dataflow example demonstrating a Frequency Shift Keying (FSK) modulation and demodulation application is also provided, offering a starting point for customers' design efforts. These components are integrated with the DRT4001 SDR RF front-end subsystem consisting of four DRT cards (Wideband Tuner, Exciter, Reference module, and the Controller) in a 20-slot 3U CompactPCI chassis. The system is flexible, scalable and can be customized as required within Spectrum's modified COTS program.

The SDR-3002 IMRDP is available for order immediately.
