A Spectrum-Efficient Cross-Layer RF Distance Bounding Scheme

<div>Similar to typical distance bounding protocols, our basic protocol design follows precommitment scheme and includes three phases. Differing from typical protocols, our exchange phase design is based on the SFCW physical layer, and the protocol that is shown here still needs further modifications to achieve secure synchronization.</div>
