Question

In a RAKE receiver, if the output from one correlator is corrupted by fading, all the other correlator’s output are also corrupted.

(a) True

(b) False

This question was addressed to me in a job interview.

This question is from Rake Receiver in section Equalization, Diversity and Channel Coding of Wireless/Mobile

Answer 1

Correct option is (b) False

To explain I would say: In a RAKE receiver, if the output from one correlator is corrupted by fading, the others may not be. And the corrupted signal may be discounted through weighting process.
