Question 3 : Consider a base station transmitting to a mobile station in free space. The following parameters relate to this communication system: Distance between base station and mobile station: 8000 m Transmitter frequency: 5 GHz Base station transmitting power, P+ = 10 W(10dBW) Total system losses: 8 dB Mobile receiver noise figure N4 = 5 dB Mobile receiver antenna temperature = 290K Mobile receiver bandwidth Bw = 1.25 MHz Antenna gains are 8 dB and OdB for the base station and mobile station, respectively. Antenna height at the base station and mobile station are 30 m and 3 m, respectively. Calculate the received signal power at the mobile receiver antenna and signal-to-noise ratio (SNR) of the received signal
