Abstract:
This paper proposes a novel means of using analog correlators to improve upon
existing Ultra-Wideband receiver architectures. Current architectures aim for an
all-digital design for the sake of ease of implementation and conceptual
simplicity. This causes some notable design challenges including an ultra-high
sampling rate, and difficulty capturing multipath energy. The architecture
outlined here, seeks to bypass some of these challenges and trade-offs by using a
receiver designed around a core of analog correlators. Although this design
abandons the conceptual simplicity of an all-digital system, it holds promise of
being able to improve upon the energy collection performance of existing Ultrawideband
receiver designs.
