#qConsider a point-to-point radio link between two highly directional antennas in a stationary
environment. The antennas have antenna gains of 30 dB, distance attenuation is 150 dB, and
the RX has a noise ?gure of 7 dB. The symbol rate is 20 Msymb/s and Nyquist signaling is
used. It can be assumed that the radio link can be treated as an AWGN channel without fading.
How much transmit power is required (disregarding power losses at TX and RX ends) for a
maximum BER of 10
