Maximum Spectral Efficiency With Adaptive MQAM Transmissions Over Terrestrial Coherent FSO Links
Himani Verma, Kamal Singh, Ranjan K. Mallik
Coherent free-space optical (FSO) communication is recognized as a key enabler for ultra-high-capacity fronthaul and backhaul links in next-generation wireless networks. Spectrally…
Maximum Spectral Efficiency of Adaptive Coherent Terrestrial FSO Links
Himani Verma, Kamal Singh, Ranjan K. Mallik
Terrestrial free-space optical (FSO) communication systems, while designed to operate on large unlicensed optical bandwidths, are fundamentally power-constrained due to stringent e…
MIMO Terahertz Quantum Key Distribution
Neel Kanth Kundu, Soumya P. Dash, Matthew R. McKay +1
We propose a multiple-input multiple-output (MIMO) quantum key distribution (QKD) scheme for terahertz (THz) frequency applications operating at room temperature. Motivated by clas…
