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 ...

Recently, intelligent reflecting surfaces (IRSs) have emerged as potential candidates for overcoming the line-of-sight issue in 5 G/6 G wireless communication. These IRSs can manipulate the direction ...

Wireless communication technologies are undergoing intensive study and are experiencing accelerated progress which leads to a large increase in the number of end-users. Because of this, the radio ...

Pulse Width Modulation (PWM) is a type of analog modulating technique in which the duration or width of the pulse changes in accordance with the time. It is a commonly used technique to produce a ...

Broadband terahertz spectroscopy enables many promising applications in science and industry alike. However, the complexity of existing terahertz systems has as yet prevented the breakthrough of this ...

The Supporting Information is available free of charge on the ACS Publications website at DOI: 10.1021/acsanm.9b00985. Smart citations by scite.ai include citation statements extracted from the full ...

In this Letter, we experimentally report an achromatic metalens (AML) operating over a continuous bandwidth in the visible. This is accomplished via dispersion engineering of dielectric phase shifters ...

The human ability to continuously track dynamic environmental stimuli, in particular speech, is proposed to profit from “entrainment” of endogenous neural oscillations, which involves phase ...

Abstract: We propose combining irregular repeat accumulate (IRA) codes with continuous phase modulation (CPM) and call this irregular repeat CPM (IRCPM). In this scheme, CPM is used as the accumulator ...

Abstract: In this paper, the problem of signal design for continuous phase modulation is examined. Using the performance measures of effective bandwidth and minimum distance, "optimal" signal shapes ...
