Question

Power delay profile is represented as plots of __________ with respect to fixed time delay reference.

(a) Relative received power

(b) Frequency

(c) Transmitted power

(d) Relative power

This question was addressed to me in final exam.

The above asked question is from Parameters of Mobile Multipath Channels in chapter Mobile Radio Propagation: Small – Scale Fading and Multipath of Wireless/Mobile

Answer 1

Correct answer is (a) Relative received power

Easy explanation: Power delay profiles are generally represented as plots of relative received power as a function of excess delay with respect to a fixed time delay reference. They are calculated by averaging instantaneous power delay profile measurements over a local area.
