Abstract
A system combining OFDM standard modulation with a superimposition of Orbital Angular Momentum modes, each OAM modes consisting in an overlapping decimated IFFTs with the main mode standard OFDM signal. Orthogonality of the OAM modes is assessed. A frame structure embodying both main mode OFDM samples and overlapping OAM modes is proposed.
