This is where a part of the wave goes through one full phase rotation. The Doppler effect or Doppler shift is the result of a wave emitting source to move causing the wavelength of the wave to stretch ...

The star Vega has been known to us for years, but that doesn't mean it's short on surprises. Here's what astronomers found ...

When NASA and the Indian Space Research Organization's (ISRO) new Earth satellite NISAR (NASA-ISRO Synthetic Aperture Radar) ...

The Creonic Doppler Channel IP core generates Doppler shift frequencies by precisely adjusting the phase of signal samples in ...

This difference is known as the Doppler shift, named after the Austrian physicist and mathematician Chr. Andreas Doppler, who first described the phenomenon for light in 1843.5 There are two ...

Abstract: Three key components in the orthogonal frequency‐division multiplexing (OFDM) receiver design are discussed in this chapter: preamble detection, synchronization and residual Doppler shift ...

The algorithm is capable of calculating the initial Doppler shift, the shift velocity and acceleration from only four consecutive phase errors. Then we present a new carrier tracking loop based on the ...

Doppler effect is a phenomenon that occurs when the relative motion between a source and a receiver of a wave causes a change in the frequency or wavelength of the wave. In wireless communications ...

Multipath occurs when a transmitted signal reaches the receiver through multiple paths, such as reflection, refraction, or scattering from objects or terrain. This results in multiple copies of ...

The Creonic Doppler Channel IP is a Doppler shift frequency (DSF) generator capable of introduce a shift frequency to samples as a phase offset. The IP was developed with the aim of allowing the ...
