Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...

Abstract: Multiple-mode orthogonal frequency division multiplexing with index modulation (MM-OFDM-IM) is a promising multicarrier transmission technique proposed recently, which focus on exploiting ...

Abstract: Ambient backscatter communication has emerged as a promising paradigm for ultra-low-power wireless systems. To support diverse IoT applications, backscatter communication should support high ...

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 ...

Prior research has investigated the integration of diverse optical communication channels. A hybrid optical communication system integrating SMF and FSO has been proposed, utilizing a configuration of ...

CP-OFDM and DFT-s-OFDM are the same waveforms that are used in 5G, giving 6G a distinctly 5G flavour in terms of the physical interface that will be developed between devices and network. That means ...

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 ...
