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 ...
Have you ever heard terms like modulation scheme, orthoganal frequency division multiplexing (OFDM), or symbol rate and scratched your head? As new wireless standards emerge, we get excited about the ...
Since the concepts of digital coding metasurface and programmable metasurface were put forward in 2014, the physical world of electromagnetics has been closely connected to the digital world of ...
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 ...
