Abstract: Though meaningful progress has been achieved for mobile wireless networks with the development of orthogonal frequency division multiplexing (OFDM) modulation, the reliability and ...

Introduction: Underwater acoustic (UWA) communication systems confront significant challenges due to the unique, dynamic, and unpredictable nature of acoustic channels, which are impacted by low ...

Meta-holograms, the computer-generated holograms assisted with nano-structured metasurfaces, promise efficient recording of light at the nanoscale. Adopting the multiplexing principle further bestows ...

Spectral purity is a signal's characteristic stability. For testing purposes, a signal must remain stable in the short and long term. Selecting a signal generator with high spectral purity ensures ...

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 ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...
