Question

Which of the following is equal to received envelope?

(a) Square of complex voltage

(b) Complex voltage

(c) Magnitude of complex voltage

(d) Magnitude squared of complex voltage

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

This interesting question is from Multipath Shape Factors for Small topic in portion Mobile Radio Propagation: Small – Scale Fading and Multipath of Wireless/Mobile

Answer 1

Right choice is (c) Magnitude of complex voltage

For explanation I would say: The received envelope is equal to the magnitude of the complex voltage. The channel is assumed to be Rayleigh fading in order to calculate the mean squared fading rate.
