Abstract:
Systems and methods for orbital angular momentum (OAM)-based multidimensional wireless communication. The OAM-based multidimensional wireless communication is preformed with a transmitter for generating an RF modulated signal carrying a data sequence. Further included is an OAM antenna array including OAM antenna elements, each of which includes an azimuthal phase shifter and an antenna element. The azimuthal phase shifter shifts an azimuthal phase term of a wavefront generated by the antenna element such that the OAM antenna element imposes the multidimensional modulated signal on a pre-determined OAM mode of a carrier signal corresponding to the azimuthal phase term.

Claim (Index 18):
The wireless communication method as recited in  claim 11 , further including receiving via a receive OAM antenna array, the carrier signal, including:\n demodulating, with a demodulator, an RF modulated signal to determine estimated constellation points, the RF modulated signal having been extracted from the carrier signal using the at least one OAM antenna element with the corresponding azimuthal phase term, the corresponding azimuthal phase term including a complex-conjugate azimuthal phase term for receiving the pre-determined OAM mode; demapping, with a demapper, the estimated constellation points by estimating symbol log-likelihood ratios (LLRs) corresponding to each of the estimated constellation points using a posteriori probability detector; and decoding, with a decoder, the symbol LLRs to determine estimated symbols corresponding to the data stream carried by the carrier signal.
