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 ...

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 ...

In the last decades, the demand for a low-cost, day-night, all-weather spaceborne imaging capability pushes to further development of synthetic aperture radar (SAR) systems, as satellite payload ...

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 ...

The Supporting Information is available free of charge at https://pubs.acs.org/doi/10.1021/acsnano.0c01269. Comparison to the previously proposed design; calculating ...

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: Advances in photonics, silicon electronics and digital signal processing (DSP) have converged to enable highly efficient transmission across fiber optic channels. Single wavelength data ...

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 ...
