Spectrum Signal Processing Integrates New Wireless Algorithms into its Software Defined Radio Platforms

BURNABY, BRITISH COLUMBIA--(CCNMatthews - June 30, 2005) - Spectrum Signal Processing Inc. (TXS:SSY)(NASDAQ:SSPI) -

New off-the-shelf options further accelerate Software Defined Radio design, development and deployment

Spectrum Signal Processing Inc. today announced the availability of off-the-shelf Field Programmable Gate Array (FPGA) algorithms for its flexComm™ product line. The addition of high performance, small footprint algorithms provide functions commonly used by waveform developers. These algorithms reduce the development time, cost and technical risks of high performance software defined radio applications.

"These FPGA algorithms are expected to allow our customers to exploit off-the-shelf front-end processing technology for projects that require complex, wide and narrowband channelization," said Mark Briggs, Vice President of Marketing, Spectrum Signal Processing Inc. "The available algorithms build on Spectrum's existing quicComm™ software and provide power efficient FPGA implementations critical to the field deployment of many defense electronic systems. With these new algorithm options, customers can choose a platform configuration more closely tailored to their application needs and allows them to concentrate on higher level design issues."

Spectrum will offer FPGA algorithms integrated into its line of software defined radio platforms as upgrade options. Available algorithms include:

- Dual channel 16K point Fast Fourier Transforms with the appropriate filtering;

- Tunable multi-channel receiver algorithms for high density, small footprint downconversion;

- Distributed half-band filters for simultaneously filtering, down-converting and decimating a real input signal; and

- Fixed-to-floating point converter algorithms.

Spectrum's software defined radio platforms with integrated algorithms are available today in Compact-PCI, PCI/PCI-X and VME configurations. For more details, visit http://www.spectrumsignal.com/products/sdr/fpga_ip_cores.asp.
