In a new study published in Nature Physics, researchers have demonstrated the Hong–Ou–Mandel (HOM) effect with up to 12 ...

Upper Row: Measurement of a scene where a ball is being thrown. While the ball's outline is blurred in the conventional method, it remains sharp in the proposed method. Lower Row: Simulation results.

For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from an ordinary handheld radio. Through a careful approach to demodulating the ...

Communication systems form the backbone of modern technology, enabling the transfer of information across various platforms. At the heart of these systems lies modulation, a technique used to encode ...

Amplitude modulation (AM) was first introduced to enable long-range wireless audio communication, representing a major advancement over wireless telegraphy using spark-gap transmitters. Understanding ...

Communicating with someone thousands of miles away is now just a few keystrokes away, thanks to the internet and other forms of communication. Modern communication leverages a variety of wired and ...

Abstract: This paper designs Bayesian iterative detection and decoding (IDD) schemes incorporating a blind channel estimator in the physical layer of long-range wide-area network (LoRaWAN). The ...

Abstract: This paper deals with discrete Fourier transform (DFT)-based modulation and demodulation techniques for affine frequency division multiplexing (AFDM), as opposed to using the discrete affine ...

Bearing condition monitoring and fault diagnosis (CMFD) can investigate bearing faults in the early stages, preventing the subsequent impacts of machine bearing failures effectively. CMFD for ...
