Abstract:
The combination of concept development, theoretical analysis and computersimulation in Phase I demonstrated the technical feasibility of the Charge Coupled
Device/Pseudo-Noise Matched Filter (CCD/PNMF) concept towards achieving a unique,
integrated receiver processing capability that encompasses PN, carrier and symbol
synchronization. Its potentially significant application to TDRSS was established,
and other possible applications were identified. The principal goal of the proposed
Phase II effort is to again focus on the CCD/PNMF Integrated Receiver (CPIR) concept
and use the solid foundation provided by Phase I as the basis for an in-depth research
and development effort, to comprehensively demonstrate the viability of the CPIR.
This is to be accomplished by a carefully selected mix of concept development, theoretical
analysis, computer simulation and laboratory hardware/software model development.
Two hardware demonstrations are proposed for presentation to NASA during the course
of the Phase II effort. If this effort is successful, the Phase III basis for expanded
research and hardware development in multiple areas will have been established, especially
in regard to advanced signal processing for the Second TDRSS Ground Terminal. Representative
areas may include: Autonomous Integrated Receiver System (AIRS), interference detection/mitigation,
and advanced processing for hybrid spread-spectrum systems.
