What is Doppler shift in wireless communication?

The Doppler shift, also known as the Doppler effect, is defined as the change in the wavelength or frequency of the waves with respect to the observer who is in motion relative to the wave source.

How do you calculate Doppler?

Doppler Effect Formula / Equation

Vr = speed of the receiver relative to the medium, +c if the receiver is moving towards the source, -c if the receiver is moving away. Vc = speed of the source relative to the medium, +c if the source is moving away -c if the source is moving towards the receiver.

How do you measure Doppler shift?

The Doppler shift can be determined after performing the range Fourier transform (range FFT) first. For a target of interest, we can repeat the range FFT until we have enough data to perform the second level of FFT.
