A wireless cellular system uses the GMS (TDMA). The bandwidth of each simplex channel is 200 kHz. The total bandwidth allocated is 200MHz . The signal-to-interference-ration required is 18 dB. Propagation path loss exponent n = 3 and omnidirectional antennas for the base stations are used. 1) Find the appropriate cluster size.2) Find the total number of available duplex channel.3) Find the number of duplex channels at each sell (single cell capacity)4) Find the cluster size when 120-sectoring antenna is used.5) Find the number of duplex channels at each sell with 120-sectoring antenna6) Find the cluster size when 60-sectoring antenna is used
The amount of sunshine on a horizontal surface at the equator is 5kWh/m2/day. Suppose a house is to run entirely off grid on solar electricity alone using a high performance silicon photovoltaic module with specifications shown below: Maximum powe..
Suppose that the amount of a weekly bill of all households is distributed with a mean of $140 and standard deviation of $35. Let X var be the average amount of bill of a random sample of 49 households selected.
Determine the input current and the load current and voltage. Also, calculate the power absorbed at the load. Use the data from A above, but assume the load is an open circuit. Determine the input current and the load current and voltag..
Derive a system diagram for a frequency-modulated transmitter and explain the function of each stage and detect and reproduce (demodulate) the message signal. Measure the frequency of the detected signal and compare that with the frequency of the m..
Use MATLAB to generate a 256x256 black image (0 values) with a 1-valued central block (white square) of 64x64 size. Analytically or graphically define/derive how to determine the rotation angles and different coordinates systems.
A 5-MVA, 66:13.2kV, three-phase transformer supplies a three-phase resistive load of 4,500kW at 13.2kV. What is the load resistance in ohms as measured from the line-to-neutral on the high-voltage side of the transformer, if it is connected in Y-Y..
A capacitor in an RC circuit with R = 5.00 ohm and C = 6.00 mF is being charged. What is the time required for the capacitor voltage to reach 86.5 percent of its steady-state value
We want to sample the 2-D continuous signal f(x,y)=exp{-\(pi(x^{2}+y^{2})\)} by means of a rectangular sampling scheme to obtain 1.5 samples per millimeter. Determine the PSF h(x,y) of an ideal low pass anti aliasing filter
Using the message signal m(t) = 1/(1+t^2) , determine and sketch the modulated signals for the following methods of modulation: (c) SSB modulation with only the upper sideband transmitted. (d) SSB modulation with only the lower sideband transmitted.
A station running TCP/IP needs to transfer a file to a host. The file contains 2048 bytes. How many bytes, including all of the TCP/IP overhead, would be sent, assuming a payload size of 512 bytes and that both systems are running IPv4
What is the maximum message bandwith for which the system operates satisfactorily? Determine the output signal to quantizing noise ratio when a full-load sinusoidal modulating wave of frequency 1 MHz is applied to the input.
