A receiver is located 20 Km away from a 40 W transmitter with respective transmit and receive antenna gain of G, = 4,G,=8. If the carrier frequency is 2000 MHz, and the degree of path loss for free space propagation is 2, Find a) The received power at the receiver [2 marks] b) The magnitude of the E-field at the receiver antenna; [2 marks] c) The open-circuit rms voltage applied to the receiver input assuming that the receiver antenna has a purely real impedance of 100 2 and is matched to the receiver; [2 marks] d) Find the received power at the mobile using the two-ray ground reflection model assuming the height of the transmitting antenna is 60 m, receiving antenna is 2 m above the ground, and the ground reflection is -1.
