Which signalling scheme is preferred for fading channel?(a) Frequency

1.	Which signalling scheme is preferred for fading channel?(a) Frequency based modulation(b) Phase based modulation(c) Frequency & Phase based modulation(d) None of the mentionedI got this question in a national level competition.This intriguing question comes from Diversity Technique and Rake Receivers in division Fading Channels of Digital Communications
Answer» Correct choice is (c) FREQUENCY & Phase BASED modulation Easiest explanation: Frequency based modulation and phase based modulation is PREFERABLE for FADING channel than amplitude based modulation.
