Consider an OFDM system operating in a channel with coherence bandwidth B. = 10 KHz. (a) Find a subchannel symbol time Ty = 1/BN = 107m, assuming Tm= 1/Be. This should insure flat-fading on the suchannels. (b) Assume the system has N = 128 subchannels. If raised cosine pulses with 3 = 1.5 are used, and the required additional bandwidth due to time limiting to insure minimal power outside the signal bandwidth is € = .1. what is the total bandwidth of the system? (c) Find the total required bandwidth of the system using overlapping carriers separated by 1/TN. and compare with your answer in part (c).
