U.S. Army Selects Spectrum's SDR-4000 for Software Defined Radio Research

COLUMBIA, MARYLAND--(CCNMatthews - Dec. 14, 2006) - Spectrum Signal Processing (USA) Inc., a subsidiary of Spectrum Signal Processing Inc. (TSX:SSY)(NASDAQ:SSPI), today announced that its flexComm™ SDR-4000 platform has been selected by the Space and Terrestrial Communications Directorate of the U.S. Army Communications-Electronics Research, Development and Engineering Center (CERDEC) for software defined radio research and development.

"Spectrum is pleased to be recognized as a leader in software defined radio technology germane to Army research and development," said Michael Farley, President of Spectrum USA. "The SDR-4000 product line has been designed for the small form-factor, rugged applications typically found in the defense sector and is also well suited for Quick Reaction Center teams with rapid deployment mandates."

The SDR-4000 is a rugged 3U CompactPCI® software defined radio platform that is comprised of two main hardware components: the PRO-4600 modem processing engine and the XMC-3321 dual transceiver input/output mezzanine module. RapidIO™ provides a high bandwidth interconnect fabric between these cards, as well as the input/output functionality to ensure the efficient use of the processing resources. Software development tools provided with this platform include Spectrum's quicComm™ hardware abstraction layer, which facilitates algorithm partitioning and programming, and a real-time operating system. The platform can be optimized for program specific size, weight, power consumption, cost and ruggedization requirements.
