Polarization diversity uses the ________ as the diversity element.(a)

1.	Polarization diversity uses the ________ as the diversity element.(a) Modulation index(b) Carrier frequency(c) Reflection coefficient(d) Coherence timeThe question was posed to me by my school teacher while I was bunking the class.This key question is from Diversity Techniques topic in chapter Equalization, Diversity and Channel Coding of Wireless/Mobile
Answer» Right answer is (C) Reflection coefficient Easiest EXPLANATION: Decorrelation of the signal in each polarization is caused by multiple reflections in the channel between MOBILE and base station antenna. Reflection coefficient for each polarization is different, which RESULTS in different amplitudes and phases for each reflection.
