The calculations show that the Doppler shift of the D3 project is about 305 kHz, and the degradation due to it is about 0.01 to 0.04 dB, which is negligible. The degradation due to frequency offset and phase noise of local oscillators will be the main source of degradation. To keep the...

It is required to estimate the emitter location using time-delay and Doppler-shift measurements realized by the receivers at successive locations along their trajectories. Most publications consider small error measurements only, and overlook the possible presence of outliers in the set of time-delay ...
They compute the time-variant Mean Doppler Shift (MDS) from the processed CSI data and magnitude from the inertial data for each sensor of the IMU. Then, various time and frequency domain features are separately extracted from the magnitude data and the MDS. The authors apply a feature-level...
trains, we then shift our focus to high velocity scenarios. such scenarios entail high temporal selectivity of the wireless channel, rendering accurate channel interpolation very important to sustain reasonable quality of service. we introduce and investigate basic concepts of channel interpolation in ...

Correction of Doppler shift and true wave spectrum The sea surface elevation extracted from the images is in a frame of reference that moves with the forward speed and heading of the ship. The directional spectrum is therefore distorted due to a Doppler shift64 and it is typically referred to...
