Multi-Waveform Wireless Prototype Will Deliver Operational Aerial Surveillance and Response ISAC is a mission-first ...

Quantum materials, materials exhibiting physical behavior governed by the laws of quantum mechanics, have proved promising ...

The development of the 6G standard is entering a more concrete phase. At the June 2026 3GPP RAN Plenary in Singapore, the industry advanced several key areas under study and finalized the timeline for ...

Abstract: Constant envelope orthogonal frequency division multiplexing (CE-OFDM) is a technique to modify the OFDM signal with high peak-to-average power ratio (PAPR) to a constant envelope zero ...

Abstract: This article proposes a hybrid dual modulation waveform pulsewidth modulation (DMW-PWM) strategy for 5L-SMC. The driver signals of each cell are generated by comparing dual modulating waves ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

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 ...

When you tune in to the radio, the announcer says, “Welcome to 100.1 FM Gold” or “You are listening to Akashvani at 783 AM”. The terms ‘AM’ and ‘FM’ refer to forms of signal modulation — a method at ...

This file type includes high-resolution graphics and schematics when applicable. Information can be sent from a transmitter to a receiver by means of modulation and demodulation, respectively, whether ...

Different types of modulation techniques are used in telecommunication for transmitting and receiving radio frequency (RF) signals. With MATLAB tools we can analyse the modulation techniques used for ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

All periodic signals can be described in terms of amplitude and phase. We all learned that in basic circuit theory. You surely recall having to calculate signal’s phase change when it passed through a ...
