Abstract:
Aspects of the present disclosure describe systems, methods, and structures that advantageously provide hybrid free-space optical (FSO)-radio frequency (RF) communication links (HFRCLs) that enable building integrated software-defined network (SDN) infrastructure capable of integrating ultra-high-throughput satellite networks, composite wireless infrastructures, heterogeneous networks (HetNets), hybrid networks, satellite networks, and fiber-optics networks—among others.

Claim (Index 5):
In a communications network comprising a plurality of nodes, said network including hybrid free-space optical (FSO) radio frequency (RF) communications links (HFRCLs) interconnecting the plurality of nodes, an adaptive, energy-efficient hybrid coded modulation technique for the HFRCLs comprising:\n using 2L-dimensional constellations for RF components; and using orbital angular momentum (OAM) coded modulation for FSO components wherein said OAM coded modulation employs an energy-efficient signal-constellation design algorithm (EE-SCDA) to obtain signal constellation coordinates including:\n 1) choosing an arbitrary auxiliary input distribution and signal constellation, where the number of constellation points M a  is larger than the target signal constellation M s , and for a uniform distribution, p i =1/M a ; \n 2) updating_Q ji  according to the following\n Q ji (t) =P ij p i (t) /\u03a3 k P kj p k (t) ; \n \n 3) updating p i  according to the following:\n p i (t+1) =e \u2212\u03bcE i \u2212H (i) (x i |Y) /\u03a3 k e \u2212\u03bcE k \u2212H (i) (x k |Y) ; \n \n where the Lagrange multiplier \u03bc is determined from the energy constraint; \n 5) determining constellation points of the target constellation from a center of mass of the closest M a /M s  constellation points in an auxiliary signal constellation; \n and repeating above steps 2-4 until convergence is reached.
