At this time, law enforcement officers and K-9 units are on campus, conducting a sweep of the area for any potential threats.

A talk, The Unreasonable Effectiveness of the Fourier Transform, was presented by [Joshua Wise] at Teardown 2025 in June last ...

Abstract: Orthogonal frequency division multiplexing with index modulation (OFDM-IM), which transmits information bits through ordinary constellation symbols and indices of active subcarriers, is a ...

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 ...

Unlike OFDM and OFDMA, both of which modulate information within the time-frequency domain, OTFS does so within the Delay Doppler domain Certain high mobility environments, such as high-speed trains, ...

Ask the publishers to restore access to 500,000+ books. An icon used to represent a menu that can be toggled by interacting with this icon. A line drawing of the Internet Archive headquarters building ...

Signal modulation identification is of high interest for applications in military communications, but is not limited only to this specific field. Some possible applications are related to spectrum ...

Abstract: In optical wireless communications (OWC), hybrid optical orthogonal frequency division multiplexing (O-OFDM) schemes, such as hybrid asymmetrically clipped O-OFDM (HACO-OFDM) and layered ...
