Question Paper
Discuss the recent advancements in wireless communication. What is frequency reuse concept? Explain with the help of a cellular diagram.
2.(a) Explain the different factors influencing small-scale fading. How are interference and system capacity related?
3.(a) What is large-scale fading? Explain its various types. Calculate the mean excess delay and rms delay spread for the multipath profile given in Figure 1. Estimate the 50% coherence bandwidth of the channel. <img src='./qimages/8834-3b.jpg'> Explain space diversity techniques In detail. Explain Linear Predictive Coders (LPC).
5.(a) Compare the various multiple access techniques.
What are the main components of a GSM system? Explain.
6.(a) What is hand-off Differentiate between hard and soft hand-off. Compare cell splitting and cell sectoring techniques to improve the capacity in a cellular system.
7.(a) Explain non-linear equalizers with its block diagram. Differentiate between Direct Sequence Spread Spectrum and Frequency Hopped Spread Spectrum modulation techniques.
8.(a) What are the different radio propagation mechanisms? Explain in detail knife edge diffraction model.
9.(a) If a transmitter produces 50 watts of power, express the transmit power in dBm, and dBW. If 50 watts is applied to a unity gain antenna with a 900 MHz carrier frequency, find the received power in dBm at a free space distance of 100 m from the antenna. What is Pr (10 Assume unity gain for the receiver antenna. Explain the characteristics of speech signals.
10. Write short notes on any two of the following:
