Q1 Capacity, Gain and Noise Figure (20 points) A base station of a cellular system radiates RF signals at P, 20W over the channel of f-1.9GHz using an antenna with the gain of 9tx 14dB. A handset is located at d-5000m away from the base station using an antenna with a gain of 9ra 3dB. 1) Find out the path loss between transmitter and receiver. 2) Find out the receiving signal power at receiver. 3) Find out the gain of the handset receiver, 9r, in order to amplify receiving signal up to 0dBm at its output. 4) Find out the SNR at the input and then output of the receiver. 5) What is the Shannon capacity of the system? (Room temperature of 290K is considered. The noise figure of the receiver is NF 14dB and channel bandwidth B=10MHz) 1
