ADC Resolution Requirement for an Intra-Quantum Signal Digitization

Résumé

This paper discusses a new approach to size an ADC for the simultaneous acquisition of two signals. It allows to evaluate the resolution which fulfills a certain dynamic range in the case of multiple signals with different powers. Experimental results with Software Defined Radios (SDR) confirm our simulations. It shows we are able to acquire an intra-quantum signal due to the contribution of a stronger transmission which makes it cross the quantization levels. Some insights about another way to exceed the theoretical dynamic range with the inherent noise in electrical systems are also provided. Thus, we propose to give the ADC required resolution to detect an intra-quantum signal when simultaneously received with a stronger one which, to the best of our knowledge, has never been thoroughly studied.
