Solve the multi-task problem: The LEO cellular satellite communication system requires the forward link (from satellite to the earth mobile) signal-to-noise ratio (SNR) in the output of the earth station receiver to be 17dB. The link has the following specifications: Operation frequency f = 6 GHz Receiver antenna gain (earth station), Gr = 0 dB Transmitter antenna gain (satellite), Gt = 3 dB Distance to satellite, d = 1000 km Bandwidth of the receiver, B = 2 MHz Noise...

Problem #2: (40 points) Consider the following communication link. Both the transmitter and receivers are properly matched to their respective antennas. Assume that the system nominal temperature is 290 K. A detailed block diagram of the receiver is shown in the figure Determine 1. The effective isotropic radiated power in dBm. 2. The space loss in dB 3. The communication link total losses in dB 4. What would be the received power at the receiver input in dBm? 5. What's...
DATA COMMUNICATIONS AND NETWORKING
In this question we will determine the maximum achievable transmission rate in the downlink of a wireless communication network. Here are the specifications of interest:- Base station (BS) transmit power. \(P_{t x}=200 \mathrm{~mW}\)- Transmitter (BS) anterma gain: \(G_{C X}=7 d B\)- Receiver (terminal) antenna gain: \(G_{\mathrm{rx}}=3 \mathrm{~dB}\)- Quality requirement: \(\mathrm{SNR}>5 \mathrm{~dB}\)- Carrier frequency: \(f=2 \mathrm{GHz}\)- Receiver noise figure: \(F=3.98=6 \mathrm{~dB}\)- Ambient temperature: \(T=290^{\circ} \mathrm{K}\)- Boltzmann constant: \(k=1.38 \times 10^{-23}\) joule \({ }^{\circ} K\)- Path loss: \(P L=\left(\frac{4 \pi}{\lambda}\right)^{2} d^{4}\)- Maximum...
