A mmW RadCom System for Short-Range Hand Gesture Sensing and Data Synchronization.
PRIME(2023)
摘要
A multifunctional transceiver for radar sensing and wireless communication (RadCom) has proven to be a valuable alternative to single-function transceivers as it enables system miniaturization and cost reduction. The use of a RadCom system for hand gesture recognition and data synchronization in smartphones could further advance smartphone development to attain another level of miniaturization. However, power consumption remains a significant concern in these applications. This paper presents a low power RadCom architecture based on a 1-bit comparator, for high resolution sensing and high data rate communication. The transmitter is able to generate IR-UWB pulses and ASK symbols. The simulation results show that data transmission can be implemented up to 5 Gbps and within a range of a few cm. The results also show that the 1-bit comparator architecture can identify three out of five fingers of the hand and accurately translate the propagation channel scenario into the range Doppler map (RDM).
