1.	The effect of Doppler shift can be counterattacked by(a) OFDM(b) By using two receivers with separate antennas(c) By using diversity receiver(d) All of the mentionedThis question was addressed to me in an internship interview.I want to ask this question from Signal Time Spreading topic in portion Fading Channels of Digital Communications
Answer» The correct option is (d) All of the mentioned The EXPLANATION: The effect of Doppler shift can be removed by using diversity SCHEME such as orthogonal frequency division multiplexing, by using TWO receivers with separate ANTENNAS or by using specially designed diversity RECEIVER.
