therefore keep the original answer sheet with you. Question No. 1: Answer the following questions? [10+5+51 [CL0 2] a) Consider your self as an engineer in a satellite company that want to provide solution to its costumer for its internet based services. After the satellite placement in orbit you are given task to work on its link budget. Provide a comprehensive report on your recommendations for the said system which must include the number of links used, frequencies used on each link, losses that occur on each link and multiple access technique used. Justify your answers with sound arguments. b) The thermal noise in an earth station receiver results in an overall (C/N)o ratio of 17dB in clear air. Likewise, a signal is received by a bent pipe transponder with an uplink (C/N)up ratio of 30 dB in clear air. If the rain causes an attenuation of 6 dB at the uplink then find downlink (C/N) dn for both clear air case and rain case. c) How can you improve the carrier to noise ratio of a satellite link, if you cannot increase the transmitted power of earth station.
