Abstract: A method for demultiplexing and demodulating (in particular, “locally” demultiplexing and demodulating) amplitude-modulated signals grouped by means of orbital angular momentum multiplexing is described. The method involves demultiplexing and demodulating information a(t), b(t) modulated on each of a first modulated beam Fm1 and at least one second modulated beam Fm2, based on phase difference values ?Pab and ?R detected by beam detectors located downstream of an interferometric structure 40 to which two portions of the electromagnetic beam carrying the modulated channels are provided as inputs, multiplexed in the orbital angular momentum variable. There is also described a corresponding system 100 for demultiplexing and demodulating amplitude-modulated signals capable of implementing the aforesaid method.
