Abstract
A differential coding system applicable to a staggered quadrature amplitude modulation transmission system is disclosed. Even when ambiguities with respect to phase and time have developed in combination in the transmission system, the differential coding system performs differential coding with ease and, thereby, faithfully regenerates an original data code sequence.
