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 ...

Variable frequency drives (or VFDs) are widely used throughout industry to provide adjustable speed control of ac motors. Although modern versions are relatively simple to install and operate, VFDs ...

With the development of the Internet and microgrids technology, a single microgrid is no longer able to meet existing energy needs. In order to improve the reliability of large-scale power supply, sub ...

In order to achieve underwater wireless dynamic optical communication, a laser communication system is proposed based on Pulse Position Modulation (PPM). In order to achieve underwater laser ...

Abstract: In this letter, a simplified soft value extraction algorithm for LDPC coded PPM modulated signals is presented. The Monte Carlo simulations are applied to get the BER curves of the system ...

Visual attention is a top–down influence affecting sensory responses in visual areas that helps us to separate relevant from irrelevant information. How is this mechanism implemented in the brain?

Neuromodulation serves as a cornerstone for brain sciences and clinical applications. Recent reports suggest that mid-infrared stimulation (MIRS) causes non-thermal modulation of brain functions.
