This alternative to time-of-flight LiDAR has unique complexities and distinct attributes. When engineers hear the phrase LiDAR, an acronym for Light Detection and Ranging, they generally think of time ...

This repository brings together the reports from three connected lab sessions on digital communications. Each builds on the previous: starting from the fundamentals of baseband coding and line codes, ...

Abstract: Conventional time-frequency analysis (TFA) methods have played an important role in characterizing the TF pattern of nonstationary signals. In this paper, a new TFA algorithm, called ...

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 ...

Abstract: Multi-input frequency shift keyying can overcome the problem of low band utilization rate in the process of binary frequency shift keyying, and has a wide practical application range. In ...

Ever wondered why the intermediate frequency (IF) in radios is fixed at 455kHz? The concept of IF is not only fascinating but highly relevant till date. To truly grasp how wireless communication has ...

RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

Ocean observation system that involves multiple underwater vehicles and seafloor nodes plays an important role in better learning the ocean, where underwater wireless communication is mandatory for ...

Transcranial alternating-current stimulation (tACS) in the frequency range of 1–100 Hz has come to be used routinely in electroencephalogram (EEG) studies of brain function through entrainment of ...
