Lockheed Martin Selects Spectrum’s SDR-3000 for Software
Communications Architecture Enabled Waveform Development

Burnaby, B.C., Canada — July 10, 2006 — Spectrum Signal Processing Inc. today announced an agreement with Lockheed Martin Corporation (NYSE: LMT) for its flexComm™ SDR-3000 software defined radio platform. Lockheed Martin will use the SDR-3000 for waveform development in a Software Communications Architecture (SCA) environment.

“Lockheed chose Spectrum for its leadership position in commercial-off-the-shelf SCA-enabled reconfigurable processing solutions,” said Russ Johnson, Principle Research Scientist at Lockheed Martin Integrated Systems and Solutions. “By selecting a Spectrum solution, I expect to advance my team’s knowledge of the SCA and SCA-enabled waveform development and accelerate Lockheed’s efforts under its next generation communications programs.”

“The SDR-3000 is an integrated subsystem that incorporates a range of software components from a number of leading vendors in the software defined radio marketplace,” said Pascal Spothelfer, Spectrum’s President and CEO. “This allows the SDR-3000 to provide all the hardware, software and design tools necessary for waveform development in an SCA environment to allow customers such as Lockheed to begin development work immediately thereby reducing their development time and risk.”

The SDR-3000 is a heterogeneous processing platform incorporating Xilinx^® field programmable gate arrays, IBM and Freescale™ PowerPC^® processors and Texas Instruments’ digital signal processors. It also includes Harris Corporation’s SCA Core Framework, VxWorks^® real-time operating system by Wind River^® and Spectrum’s quicComm™ hardware abstraction layer, which facilitates algorithm partitioning and programming with a real-time operating system. The SCA is an open architecture developed by the U.S. Department of Defense for its Joint Tactical Radio System program.

Aselsan Selects Spectrum’s Platform for Software Communication
Architecture Development

Burnaby, B.C., Canada — July 19, 2006 — Spectrum Signal Processing Inc. today announced that Aselsan will use Spectrum’s flexComm™ SDR-3002 IMRDP platform for research and development of software defined radio (SDR) and Software Communications Architecture (SCA) technologies. Aselsan is the leading Turkish electronics company that designs, develops and manufactures modern electronic systems for the military and aerospace market.

“This contract establishes our presence in Turkey, a country that supports the second largest defence force in NATO after the United States,” said Dan Simard, Managing Director of Spectrum Signal Processing (UK) Limited. “We will continue to pursue other opportunities in Turkey with both our non-rugged and rugged product families.”

The SCA is an open architecture framework that tells designers how elements of hardware and software are to operate in harmony. Originally developed for the US Department of Defense Joint Tactical Radio System program, the SCA is being adopted worldwide as a standard technology for software defined radios.

The SDR-3002 IMRDP is a commercial-off-the-shelf (COTS) solution specifically targeted at international military communications programs. The platform provides a turnkey black-side “RF to Ethernet” processing system and includes sample application software supporting frequency agile operation, making the SDR-3002 IMRDP ideal for rapid-prototyping, development and deployment of both wide and narrowband waveforms. Also included are an SCA Core Framework, a real-time operating system and Spectrum’s quicComm™ hardware abstraction layer, to facilitate algorithm partitioning and programming. These components are integrated with Digital Receiver Technology, Inc.’s DRT4001 SDR RF front-end subsystem, which includes a wideband tuner, exciter, reference module and 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.

For more information on the SDR-3002 IMRDP, please visit www.spectrumsignal.com/products.

Spectrum Signal Processing Signs Agreement For Cognitive Radio
Research and Development

Burnaby, BC — July 24, 2006 — Spectrum Signal Processing Inc. today announced a $500,000 agreement with Motorola, Inc. for the supply of its flexComm™ SDR-3000 SMRDP.

“This agreement is significant because it provides Spectrum with valuable insight into how the public safety and homeland security markets are adopting software defined radio and cognitive radio technologies,” stated Pascal Spothelfer, Spectrum’s Chief Executive Officer.

A cognitive radio is a type of software defined radio that is able to reconfigure its analog radio frequency (RF) output and incorporate “self-awareness” and knowledge of transmission protocols, etiquette and procedures. By sensing its RF environment and location, a cognitive radio is able to alter its power, frequency, modulation and other operating parameters so as to dynamically reuse whatever radio spectrum is available.

Spectrum’s SDR-3000 SMRDP is based upon its SDR-3000 software defined radio processing and analog-to-digital/digital-to-analog converter boards in a four slot 2U CompactPCI^® chassis. These components are integrated with two RF transceiver subsystems in a 20-slot 3U 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 a Software Communications Architecture Core Framework. The system is flexible, scalable and can be customized as required. For more information on the SDR-3000 SMRDP, please visit www.spectrumsignal.com/products.
