Which of the factor does not determine the correlation coefficient?(a)

1.	Which of the factor does not determine the correlation coefficient?(a) Polarization angle(b) Cross polarization discrimination(c) Offset angle from the main beam direction(d) Coherence timeI have been asked this question in a national level competition.Asked question is from Diversity Techniques in division Equalization, Diversity and Channel Coding of Wireless/Mobile
Answer» Right choice is (d) Coherence time Easiest explanation: The correlation coefficient is determined by three factors, polarization angle, OFFSET angle from the main beam direction of the DIVERSITY ANTENNA, and the cross polarization discrimination. The correlation coefficient generally becomes higher as offset angle becomes large.
