Doppler shift is directly proportional to __________

B. Height of antenna

C. Power of receiving antenna

D. Power of transmitter

I have been asked this question by my college professor while I was bunking the class.

The doubt is from Small- Scale Multipath Propagation in section Mobile Radio Propagation: Small – Scale Fading and Multipath of Wireless/Mobile

Right answer is A. Velocity

Explanation: The shift in received signal frequency due to motion is called Doppler shift. It is directly proportional to the velocity and direction of motion of mobile with respect to the direction of arrival of the received multipath wave.
