system is illustrated in the fol- lowing figure. The uplink portion will be analyzed in this problem. The output power of the ground transmitter is 200 W. This power level is effectively increased in the di- rection of transmission by the ground antenna, which has a gain of 40 dB. The transmitted signal is attenuated by a path loss of 200 dB. The receiver antenna gain is 20 dB. (a) Determine the received signal power in femtowatts and in dBf. (b) If the total noise level at the input to the satellite receiver is 8 dBf, determine the received signal- to-noise ratio in dB. 1-31 A satellite communication Geostationary Communication Satellite Transmitting Earth Station LORS 100 Receiving Earth Station system is illustrated in the fol- lowing figure.
