6.8.1. Consider a system that uses noncoherently demodulated BFSK with a bit error probability of 10−4. The data rate is 25 Mb/s. The transmit and receive antennas are identical. The link margin is 3 dB, and other losses are 2 dB. The distance between transmitter and receiver is 14 km, and the system effective temperature is 400 K. The transmit power is 1.5 mW, and the carrier frequency is 4.5 GHz. (a) Determine the path loss in dB. (b) Determine the required Eb/N0 in dB. (c) Determine the antenna gains. (d) Determine the antenna diameters assuming the efficiency is 0.55.
