Define the terms fundamental frequency, spectrum, and absolute bandwidth of a signal.

A signal has a fundamental frequency of 1000 Hz. What is its period?

Assume the signal has a peak amplitude of 1 Volt and that the instantaneous power is equal to the square of the voltage, then compute the average power of the fundamental frequency component of the signal.

When the signal is transmitted, the measured power at the receiver is 0.25 W. Express the power loss in decibels.

What role does FCC play in spectrum allocation and why is it important? Select one of ISM, UN-II, and licensed bands, including the wireless applications assigned to that band.

A stationary transmitter has a center frequency of 2 GHz. Compute the maximum and minimum spectral frequencies received by a mobile travelling at a speed of 100 km/hr. What is the frequency of the received signal if the mobile is moving in a direction perpendicular to the direction of arrival of the transmitted signal? Justify your response using your knowledge of Doppler shift.

Define coherence time. How is it related to Doppler spread?

List the various types of small scale fading mechanisms and identify whether each one is created by multipath propagation or Doppler spread. Select one of the fading types and describe the conditions under which it occurs and how the received signal is affected by that fading mechanism.

List the wideband channel sounding techniques for determining the small-scale fading effects. How do these techniques quantify the fading effects? Select one of the techniques and describe how it is used to measure the small-scale-fading effects.

List the wideband channel sounding techniques for determining the small-scale fading effects. How do these techniques quantify the fading effects? Select one of the techniques and describe how it is used to measure the small-scale-fading effects.

Define the terms mean excess delay, rms delay spread and the coherence bandwidth of a communication channel.

The local average power delay profile inside a building is given by:

Tabulate the Power Delay Profile of the channel in dBm. Use n = 0 as the reference.

b. Compute the mean excess delay and rms delay spread of the channel.

c. If GSM requires a 200 kHz bandwidth, determine whether this channel is suitable for GSM service without the use of an equalizer.
