1.	Coherence time refers to ____________(a) Time required attaining a call with the busy base station(b) Time required for synchronization between the transmitter and the receiver(c) Minimum time for change in magnitude and phase of the channel(d) None of the mentionedThis question was addressed to me in final exam.My query is from Modulation Performance in Fading and Multipath Channels in section Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» Correct OPTION is (B) Time required for synchronization between the transmitter and the receiver Explanation: COHERENCE time is the time required for synchronization between the transmitter and receiver. It is the over which a propagating wave is said to be COHERENT.
