Distributed wireless clock synchronization is essential for aligning the clocks of distributed transceivers in support of joint transmission and reception techniques. One recently explored method involves synchronizing distributed transceivers using a two-tone waveform, where the tones are separated in frequency by a clock (frequency) reference signal. Prior research has demonstrated frequency accuracy better than 1 Hz; however, this approach remains vulnerable to both intentional and unintentional interference. In this demonstration, we present a robust, frequency-hopped two-tone waveform that enables transceivers to extract the reference signal without prior knowledge of the exact frequency at which the tones are transmitted.
