Abstract [en]
To overcome the dynamic range problems that conventional coarse quantized analog-to-digital converters (ADCs) suffer from, we consider the modulo ADCs with known folding-count (Mod-ADC-K). Two Cramér-Rao bounds (CRBs) are derived for signal parameter estimation from data generated by Mod-ADC-K, for both quantized and unquantized cases. Then we analyze their characteristics, and compare them to the conventional ADCs. Numerical examples are presented to verify the characteristics of Mod-ADC-K, and show that the low-bit Mod-ADC-K can mitigate the dynamic range problems.
