Spectrum Signal Processing Introduces Latest Rapid-Prototyping Platform for Communications Intelligence Applications

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 flexComm™ HCDR-1000 CRDP, a communications intelligence (COMINT) rapid-prototyping and development platform. This fully integrated, commercial-off-the-shelf (COTS) software defined radio platform is designed to promote the rapid development and deployment of intelligence systems for the intercept and processing of communications signals. It is comprised of a high-speed dual channel analog-to-digital converter, multiple Xilinx® Virtex-II™ and Freescale™ PowerPC® processing elements, and dual VME-based carrier boards.

The HCDR-1000 CRDP provides the hardware, software and development tools necessary to begin immediate development of COMINT systems. The platform's architecture was specifically designed to support the simultaneous detection and processing of multiple wideband and narrowband signals, including complex signals incorporating frequency agility (frequency hopping) and direct sequence spread spectrum. Real-time performance is maintained by the HCDR-1000 CRDP through the use of multiple subsystems operating in parallel, including:

- A wideband spectral analysis subsystem that can detect and parameterize signals of interest, including identifying the center frequency, received signal power and spectral shape of each detected signal.

- A delay-buffer and channelization subsystem that can be used to extract potentially hundreds of baseband signals of interest from the incoming IF signals without incurring data loss.

- A baseband channel processing subsystem that can be used to identify the modulation schemes of the signals of interest and potentially recover the underlying data.

- A real-time high-speed disk storage subsystem allowing extended recording of IF signals for offline playback at a later time.

"Our goal in designing the HCDR-1000 CDRP was to accelerate the field deployments of our COMINT customers," said Mark Briggs, Spectrum's Vice President of Marketing. "The platform supports multi-channel development using a highly scalable and modular architecture. After the application software is developed, the platform can be fielded as-is in many COMINT settings as an integral part of a deployment system. In addition, through Spectrum's modified COTS program, the platform can be customized to allow developers to further mitigate technical, cost and schedule risks throughout the development and deployment of their complex COMINT programs. The HCDR-1000 CRDP joins our other application-specific platform offerings for military communications, electronic intelligence and satellite communications."

The package includes Spectrum's quicComm™ software, a hardware abstraction layer that facilitates platform programming and code portability. Comprehensive software examples that demonstrate application data flows are also provided to simplify and accelerate development initiatives. Technical support services and training courses are part of this comprehensive product offering.
