b • Preliminary Design and Implementation of the Baseline Digital Baseband Architecture for Advanced Deep Space Transponders

This article investigates and identifies the baseline design and implementation of the digital baseband architecture for advanced deep space transponders. Trade studies on the selection of the number of bits for the analog-to-digital converter (ADO) and optimum sampling schemes are presented. In addition, the proposed optimum sampling scheme is analyzed in detail. Descriptions of possible implemen-tations for the digital baseband (or digital front end) and digital phase-locked loop (DPLL) for carrier tracking are also described
