Generation of OFDM Signal] Using the 16-point QAM signal constellation shown in Figure 7 .21, select pseudorandomly each of the information symbols X1,X2, ... ,Xg. With T = 100 seconds, generate the transmitted signal waveform x(t) given by (8.2.3) for t = 0, 1, ... , 100 and plot it. Then compute the IDFT values Xn, for n = 0, l, ... ,N - 1, by using (8.2.2). D emonstrate that x(t), evaluated at Tn/N, n = 0, 1, ... ,N - 1, corresponds to the IDFT values. Finally, using the IDFf values {Xn, 0 ≤ n ≤ N - 1}, compute the DFf, defined as
![]()
and, thus, demonstrate that the information symbols {Xk, 1 ≤ k ≤ 9} are recovered from the samples of x(t), where ![]()
