Question

If the bandwidth transmitted signal is smaller than the bandwidth, then the signal could be severely influenced by frequently selective fading flat fading fast fading slow fading There is a dB per decade attenuation is signal strength as a function of distance in free space propagation 6 20 12 40 For space diversity technique, they separation between antenna 1 lambda 2 lambda 5 lambda none of them Selection combining technique is using at the receiver Variance SNR Max SNR Mean SNR None of them A antenna which attempts to direct all its energy is a particular direction is called as a Directional Antenna One to One Antenna Propagation Antenna Single Directional Antenna GSM is the accepted cellular standard in Europe South America Southeast Asia All of the above Ricean distribution model is an example of Small scale fading large scale fading free apace model All of the above is a famous large scale path propagation model Mala scale fading 2 was propagation model free space model None of the those Multiple knife-edge model phenomena is function of Scattering Diffraction Reflection All of the above The interference between the neighboring base stations is avoided by Assigning different group of channels Using transmitters with different Using different antennas All of the above

Explanation / Answer

Solution:

1. b) flat fading

If the bandwidth of the transmitted signal is lower than the coherence bandwith, only the gain and phase of the signal are changed, and nonlinear transformation cannot occur. Ths is called flat fading.

2. c) 20

There is a 20 dB per decade attenuation in signal strength as a function of distance in free space propagation.

3. c) 5

For space diversity technique, the seperation between antenna 5

4. b) Max SNR

5. a) Directional Antenna

A antenna which attempts to direct all its energy is a particular direction is called as a Directional Antenna.
