- 11-2) Now consider that white noise (i.e., noise with a PSD that is constant with frequency) is introduced in the channel of the system described in the previous problem. An ideal low pass filter is used at the receiver input to reduce the noise as much as possible, while transmitting the desired signal. (a) By what factor should the cutoff frequency of the noise reduction filter be reduced in the 16-PAM case, compared to binary? (b) By what factor will the noise power at the decision circuit be reduced in the 16-PAM case? (c) By what factor will the noise amplitude at the decision circuit be reduced in the 16-PAM case? (d) To obtain the same symbol error rate for 16-PAM as for binary, how should the minimum level spacing for 16-PAM compare to binary? (e) If the 16-PAM level spacing is adjusted according to part (d) above, by what factor will the average signal power be increased in the 16-PAM case, compared to binary?arrow_forward11-1) similar to Lathi & Ding, Prob. P.6.7-5 Data at a bit rate Rb must be transmitted using either binary NRZ polar signaling or 16-ary PAM NRZ polar signaling. (a) By what factor will the symbol rate be reduced in the 16-PAM case? (b) By what factor will bandwidth required from the (lowpass) channel be reduced in the 16-PAM case? (c) Assuming the minimum spacing between pulse levels must be the same in both cases, by what factor will the average power be increased in the 16-PAM case? [Hint: take the pulse amplitudes to be ±A in the binary case, and ±A, ±3A, ±5A,..., ±154, and recall that scaling pulse amplitude by a factor k scales the pulse energy by a factor R². Assume that the data is random, so that all 16 levels are equally likely, and that the same pulse shape is used in both cases.] Warning: Solutions to the textbook problem that are posted online are mostly wrong.
