Question: Repeat Illustrative Problem for a channel with bandwidth W multipath spread Tm = 10 µs and a Doppler spread Bd = 10 Hz.

Problem: Suppose a communication channel having a bandwidth W = 10 kHz is characterized as a multipath channel with multipath spread Tm = 10 ms and a Doppler spread Bd = 0.1 Hz. Select the parameters of an OFDM system such that the bandwidth loss due to the cyclic prefix (or time guard band) does not exceed 10%.
