Topic:

An Equivalent Baseband Signal Model for Rydberg Atomic Quantum Receiver (RAQR) Aided Wireless Communications and Sensing 

Abstract:

Rydberg atomic quantum receivers (RAQRs) emerge as a radical solution for detecting radio frequency (RF) signals, showing great potential in assisting classical wireless communications and sensing. However, the current studies of RAQRs mainly focus on realizing fundamental functionalities via experiments, where the results are indirect in assisting wireless communications and sensing. Moreover, the advantages of RAQR based wireless receivers have not been fully unveiled. To fill the gap, we introduce the superheterodyne of RAQRs to the wireless systems by presenting an end-to-end transmission scheme. We then develop a corresponding end-to-end equivalent baseband signal model based on a realistic transmission flow. Our scheme and model provide explicit design guidance to RAQR-aided wireless systems, and allow various signal processing in an easy-to-handle way.
