As satellite communications constellations grow in size and number, they are also competing for a scarce and increasingly valuable resource: spectrum, the bands of radio frequencies that are crucial ...

Fundamentally, every active sensing system, be it monostatic or bistatic in configuration, is a communication system consisting of a transmitting source and a receiver. Owing to advances realized in ...

GEO-82, inspired by the beloved ride, is set to open this year and will offer reservations for park guests ages 21 and older, according to a post on the official Disney Parks Blog. The new adults-only ...

Earth's natural 'humming' vibration has experienced a series of unusual spikes in recent weeks, raising questions about whether the phenomenon could influence mood and cognition. Known as the Schumann ...

Microwave photonics is the practical application of electromagnetic waves with a wavelength between one millimetre and one meter. Microwaves are important for communications, and systems for detecting ...

KENNEDY SPACE CENTER — While giving an update on the Artemis II rocket and its repairs, NASA Administrator Jared Isaacman revealed that the Artemis III mission will not be landing on the moon.

Abstract: This paper investigates sample vector normalization as a statistical preprocessing technique for cooperative spectrum sensing under realistic direct-conversion receiver (DCR) impairments. A ...

Abstract: This letter proposes the Laplacian kernel correlator (LKC) to address the limitations of current spectrum sensing techniques in the presence of Laplacian noise interference. The proposed ...

DSS lets 4G LTE and 5G NR run simultaneously within the same frequency band. It does this by dynamically distributing Resource Blocks (RBs), the fundamental units of spectrum assignment, between the ...
