8/29/2003 - Spectrum Signal Processing Inc. (NASDAQ: SSPI / TSX: SSY), a leading provider of high performance solutions for wireless signal and packet-voice processing, announced that it will be providing a software defined radio (SDR) demonstration system running a wideband, ad hoc networking waveform based on orthogonal frequency division multiplexing (OFDM) to a leading provider of software defined radios to the military. The solution will be based on Spectrum’s flexComm SDR-3000 family of software defined radio platforms and will provide the testbed demonstrating support of high bandwidth communications in a mesh network of radios. A mesh network is an area network whereby users are connected to each other without the need for a central communications hub. Mesh networks offer reliability and redundancy since if one radio ceases to operate, other radios can continue to communicate directly or through one or more intermediate radios. This is the concept behind the Wideband Networking Waveform (WNW), a critical new waveform for the Joint Tactical Radio System (JTRS).
“It is extremely satisfying to have another U.S. defense contractor validate Spectrum’s leadership position in software defined radio platforms,” said Sean Howe, Vice President and General Manager of Spectrum’s Wireless Systems Group. “We are pleased to be able to support our client’s efforts in SDR by developing and demonstrating a wideband, ad hoc networking waveform. Being selected by our client to provide this type of solution validates our strategy to offer our customers Application Engineering Services that complement our hardware platform offering.”
Spectrum’s hardware platform was chosen on the basis of flexibility and performance. The ability to network different types of processors, including state-of-the-art XilinxTM Field Programmable Gate Arrays, Texas Instruments Digital Signal Processors, and PowerPCTM processors from Motorola and IBM, to handle all the waveform processing was of critical importance to the client. Spectrum’s Application Engineering Services team complemented the value of the hardware platform by demonstrating a thorough expertise of the waveform requirements and by offering a development plan that significantly shortened the client’s time to market.
OFDM is a technology that transmits data simultaneously over a large number of channels at different frequencies, enabling high bandwidth communications. This digital modulation/demodulation technique is highly spectral efficient and resilient to interference which results in better signal reception and reduced probability of intercept.
