- 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.arrow_forwardSolve it fast fast plzarrow_forwardThe scattering parameters of a certain two-port network is measured to be [0.3 0.6] using 50 ohms measurement system.M=0.4 [s] = M 0.2 a) Find equivalent impedance (Z) parameters for this network. b) What would be the scattering matrix if 100 ohms measurement system is used?

- 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 bandpass filter circuit is used in the filter method to reject one sideband and transmit the remaining sideband. The modulating signal and carrier are applied directly to one of the modulators in the phase-shift method, then both are moved 90 degrees and applied to the second modulator. The outputs of the two balanced modulators are double-sideband suppressed-carrier signals with the proper phase, so that one of the sidebands is canceled when they are combined in a linear summer. The disadvantage of single-sideband transmission is which of the following statements? Select your answer. Tuning single-sideband receivers is more difficult and precise than tuning DSBSC AM receivers. Because most single-sideband transmissions involve a suppressed carrier, envelope detection cannot be employed unless the carrier is…arrow_forward
