A transmitter with power output .75 watts operates at 1090 MHz. The transmit antenna gain is 2.1dB, and the receive antenna gain is 1.6dB. The received is 18Km away from the transmitter. The receiver has a Noise Figure of 8dB, Bandwidth 1.7 MHz and the Data Rate is 640K bps. You may assume T0 = 290K. Assuming no other noise sources or losses, calculate the received Eb/N in dB.
