In the next-generation radio access network (NG RAN), the next-generation evolved NodeBs
(gNBs) will be, likely, split into virtualized central units (CUs) and distributed units (DUs) …

This paper investigates the transmission performance of a 1.55-Tb/s Nyquist-wavelength
division multiplexing superchannel along with a mixed line rate approach using 4× 111 Gb/s …

Visible light communication (VLC) employs light emitting diodes (LEDs) to provide
illumination and data communications simultaneously. Organic LEDs (OLEDs) employing …

High-order modulation signals are suited for high-capacity communication systems because
of their high spectral efficiency, but they are more vulnerable to various impairments. For the …
