Orthogonal frequency division multiple access (OFDMA) is a version of OFDM (orthogonal frequency division multiplexing) modulation that happens to be optimized for multiple users, specifically for ...

Index modulation (IM) in orthogonal frequency division multiplexing (OFDM) systems represents a transformative approach in modern communications. This technique utilises the indices of active ...

Abstract: While many questions still surround the creation and deployment of the smart grid, the need for a reliable communications infrastructure is indisputable. Developers of the IEEE 1901.2 ...

Copper cabling has been the workhorse for moving data inside of AI and HPC data centers, but fiber is nipping at its heels. Optics brings three possible bandwidth multipliers — wavelength-division ...

Advancements in photonic integration demand high-speed, precise dynamic light field control and large-capacity information processing capability. As subwavelength artificial structures, metasurfaces ...

In high-speed optical communications, traditional orbital angular momentum (OAM) multiplexing systems face fundamental limitations, including ...

5G New Radio (5G NR) is the wireless standard defining the next generation of mobile networks. 5G will offer higher capacity than current 4G, enabling a higher density of mobile broadband users and ...
