Low-light image enhancement (LLIE) aims at improving the perception or interpretability of an image captured in an environment with poor illumination. Recent advances in this area are dominated by …
A new techniqueto detect the phase difference of two high-frequency RF signals is presented. It is based on downconverting the two high-frequency input RF signals into two low-frequency signals via…
For 6G in 2030 and beyond, key performance metrics long for terabit-per-second, one-tenth of millisecond latency with zero jitter, millimeter-preci-sion sensing and positioning, and seamless connec…
Recently, significant research attention has been devoted to the study of reconfigurable intelligent surfaces (RISs), which are capable of reconfiguring the wireless propagation environment by expl…
A Serrodyne microwave frequency translator implemented using a microwave photonic technique is presented. It is based on two dual-drive Mach-Zehnder modulators connected in parallel where one of th…
High-order random fiber laser amplification (RFLA) is an effective way for realization of ultralong optical transmission and sensing. However, potential issues such as modulation instability (MI) a…
