摘要

A digital wireless information transmission system comprising at least one optical infrastructure (1, 4b) for the generation, coding, modulation and demodulation of a wireless signal, at least one wireless electrical transmission and reception system (3a, 3b) and less an interface (2, 4a) between each optical infrastructure and each electrical system, characterized in that the optical structure is adapted to perform a differential multilevel modulation by phase shift. Thanks to this system, high spectral efficiency is achieved without the need for synchronization of the carrier. (Machine-translation by Google Translate, not legally binding)
