==Original Abstract Submitted==

a computational method to estimate the carrier frequency offset (cfo) of wireless communication systems using novel phase measurements is disclosed. the computation is carried out in the diophantine framework defined in this disclosure. it effectively resolves the phase ambiguity (due to 2� crossing) commonly embedded in the phase measurements. the phase ambiguity is an issue for wireless packet communications when a significant initial cfo cannot be synchronized reliably to a common reference packet per packet. a typical application is vehicle to everything (v2x) communications employed by the intelligent transportation systems (its) worldwide, as included in the ieee 802.11 wlan standard as well as in the 3gpp lte and 5g standards. an emerging application that needs to address high doppler frequency is non-terrestrial network (ntn) in 5g wireless communications. the disclosed computational framework offers scalable computational complexity for implementation tradeoff to meet both cost and performance requirements.
