6-1. You are designing an FDM-PCM/FDMA analog link that will occupy 36 MHz of an INTELSAT VI transponder with 10 users of equal bandwidth. The uplink and downlink center frequencies of the occupied band are 5985.5 MHz and 3760.5 MHz. The distance from the satellite to your earth station is 40,000 km. The saturation uplink flux density (total - all carriers) for your uplink is - 75 dBW/m2 and the satellite's G/T is = -11.6 dB/K. At saturation, the transponder EIRP for your downlink is 29 dBW and the earth station's G/T is 41 dB/K. Assume that the transponder is linear (an unrealistic scenario - but do it this way such that BOI = BOo, dB. The intermodulation carrier to noise ratio, (C/N), in dB, is related to the back-off BOo in dB by (C/N)31M = 7.86 - 0.714 * BO0 In other words, at Xponder saturation the value of (C/N)31M = 7.86 dB and for example BOo = -6 dB the (C/N)31M = 7.86 0.714*(-6) = 12.14 dB. (a) Find the maximum overall carrier-to-noise ratio (C/N), in dB that this link can…
Ans. (10 W 3.4.3 A 15 km optical fiber link uses fiber with a loss of 1.5 dB km '. The fiber is jointed every kilometer with connectors which give an attenuation of 0.8 dB cach.

During the first month of work, you get an assignment to perform a measurement campaign to estimate the channel path loss exponent for a new wireless product. You performed field measurements and collected the following data: Reference path loss: PL(d0) Path loss measurements: PL (d1), PL (d2), ... PL (dn), at distances d1 … dn Using the path loss exponent model, find an expression for the optimum value of the path loss exponent n, which minimizes the mean square error between measurements and the model. Hint: the optimum value of n should minimize the mean square error (MSE) between your predicted path loss and measured path loss.
