analysis for the wireless system, which will involve calculating
the following:
• Received Power
• Link Margin
Assume that we are using the same antennas at the transmitter
and the receiver side, the link budget calculations will be the
same as the link budget in both directions is expected to be
symmetrical. In cases where 2 types of antenna systems with
different transmit power are used, we must perform two link...

[Communications Link Problem ]During design of your satellite
you discover a readily available antenna that weighs the same as in
the original design but has a diameter twice as large. Assuming
this size increase is NOT a problem how much can you reduce the
transmitter output power from the original design of 50 watts
assuming the same data rate, bit error rate, and link margin?

A broadcaster transmits its program over a geosynchronous satellite. The uplink and downlink carrier frequencies are 14 GHz and 12 GHz, respectively. The distance from the satellite to the gateway and the the receiver can both be approximated as 36,000 km. Assume that the uplink (the Gateway) antenna has a gain of 40 dBi, the receiver on the satellite has an antenna with a gain of 20 dBi and a noise temperature of 3500 K. The video encoder’s rate is...

Problem 8 Communication Link: Gain & Loss (14 points) You are given the receiver block as schematically shown below. It consists of a receiving antenna which delivers a signal to a bandpass filter. The antenna feed has a loss of -1.15 dB and the filter's loss is -2.4 dB. The filter's output drives an amplifier with gain of +40.7 dB and this RF signal is input to a mixer which performs a frequency 1translation to an IF signal (but the...
