In the last couple of decades, terahertz (THz) technologies, which lie in the frequency gap
between the infrared and microwaves, have been greatly enhanced and investigated due to …

This paper reviews the foundations of the Kramers–Kronig (KK) receiver, a recently
proposed scheme designed to reconstruct a complex-valued signal from the measurement …

Future wireless communication networks will need to handle data rates of tens or even
hundreds of Gbit s− 1 per link, requiring carrier frequencies in the unallocated THz …

Modern communication systems rely on efficient quadrature amplitude modulation formats
that encode information on both the amplitude and phase of an electromagnetic carrier …

Photonics might play a key role in future wireless communication systems that operate at
terahertz (THz) carrier frequencies. A prime example is the generation of THz data streams …

The use of advanced digital signal processing (DSP) technology in the high‐speed terahertz
(THz) communication can effectively compensate the linear and nonlinear effects of the …

Infrared free-space optics (FSO) provide an attractive solution for ultra-high-capacity
wireless communications. However, the full potential of FSO is still being hindered by the …

We propose an indoor network with a sub-terahertz-band wireless link for 6G applications. In
our proposed indoor network, an optical hub unit (OHU) that controls the entire system is …

Integrating sensing function is becoming a key feature in the sixth generation (6G) radio
access network. In this paper, we proposed and experimentally demonstrated a novel …

We investigate the feasibility of pulse amplitude modulation-N (PAM-N) signal transmission
over a photonics-based cost-effective THz wireless link. A direct detection-based THz …
