Field Programmable Gate Array Based Channelizer

Transformational Communications require the development of a reconfigurable low power radiation hardened channelizer capable of scaling up to support 25 20 MHz narrowband and wideband channels. Field Programmable Gate Array (FPGA) technology is ideal for rapid development of customizable circuit. Xilinx and Actel are the only vendors with radiation hardened FPGA having over a million usable gates count. Xilinx FPGA is based on SRAM technology which requires Triple Modular Redundancy (TMR) to eliminate Single Event Upset (SEU) while Actel FPGA is based on anti-fuse technology with triplicated gates. LinQuest is proposing to use Xilinx QPRO-R FPGA to satisfy Transformational Communications Channelizer requirement. This proposal will also review various channelizer architectures and implementations approaches. The final architecture will be simulated in C/C++, MatLab, and Verilog/VHDL. The channelizer design will be synthesized and routed for the purpose of accessing resource utilization, power consumption, and maximum clock speed. The final analysis will be Phase I deliverable. LinQuest is an employee-owned small business with exceptionally strong qualifications in the Military & Commercial Satellite Communication Systems, Engineering and Technical Assistance (SETA) arena. LinQuest has over 20 years of experience development state-of-the-art end-to-end simulation platforms (MEESE) providing SETA support for Milstar, AEHF, and now Transformational Communications (TSAT). Over the years, LinQuest has developed a library of channelization capabilities including channel coding, modulation, fading, jamming, and nuller functionalities. LinQuest's engineers hold advance degrees and have extensive experience in flight hardware design including AEHF transponder and channelizer. Thus, LinQuest is uniquely qualified to support the development of Transformation Communications Channelizer.
