Abstract:
Systems and methods for orbital angular momentum (OAM)-based multidimensional signaling with multiple-input-multiple-output (MIMO). The wireless communication is achieved using a transmitter including a plurality of orthogonal pulse shapers of a multidimensional modulator, the plurality of orthogonal pulse shapers generating a multidimensional modulated signal by imposing one or more data sequences on corresponding mutually orthogonal filter impulse responses derived from multiple orthogonal basis functions including Slepian sequences. An OAM antenna array including OAM antenna elements is used such that each of the OAM antenna elements includes an azimuthal phase shifter for shifting an azimuthal phase term of a wavefront generated by an antenna element such that the OAM antenna elements impose the multidimensional modulated signal on pre-determined OAM modes of a carrier signal corresponding to the azimuthal phase term.

Claim (Index 8):
The wireless communication system as recited in  claim 1 , further including a receiver including a plurality of orthogonal matched filters, wherein receiver is configured to receive the carrier signal via a receive OAM antenna array, the receiver further including:\n a multidimensional demodulator configured to demodulate a multidimensional modulated signal by calculating projections along the multiple orthogonal basis functions using the plurality of orthogonal matched filters configured to match the plurality of orthogonal pulse shapers, to determine estimated constellation points, the multidimensional 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; a demapper configured to demap 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 a decoder configured to decode the symbol LLRs to determine estimated symbols corresponding to the data stream carried by the carrier signal.
