Question 3) A transmission occupies the spectrum between 15 MHz and 20 MHz. Assume that the signal is being
transmitted at a power level of 20dBm. Answer the following:
1) If the signal is received attenuated by 13dB, what is the acceptable noise level at the receiver to allow a
maximum capacity of 10Mbps?
SMR
Dandeadu
2) If the noise is at it maximurh acceptable value (calculated in part 1), what is the needed number of signal
levels to encode the data at 10Mbps?
Nyquist Bitrate (a XB)( log (L)
TOM = 2(5H) log,CL)
%3D
L= 2 lends
3) If the noise power at the receiver is 0.2 mW, how will the capacity be affected and what is the needed
number of encoding levels to achieve this capacity?
