Question2: 5G link (40 pt) In this question we want to explore 5G as the next evolution in cellular communications. One proposal would be a wireless link designed at the 28

GHz band to transmit at 4 Gbps bit rate over a 1 GHz channel. a) What would be the minimum number of bits per symbol? Suggest a constellation. (10pt) b) What is the sensitivity required for the receiver given a BER of 10 -6? Assume the noise figure of the receiver is 7dB. (you can find BER vs SNR plot lecture notes) (10pt) c) If the maximum PA output power is 23 dBm, what is the distance that can be supported? (you can find PAPR data in lecture notes). (10pt)
