Note: Conduct the following experiments to implement the indicated communication processes by simulation using MATLAB or any equivalent tool.
Laboratory Experiments
1. Develop a code to compute the Path loss, Link Budget and sketch relevant plot.2. Develop a code to represent the different channel models for wireless networks.
3. Analysis of cellular concepts like cell-sectoring, splitting (using Qualnet/ NS3/ any other tool).
4. To consider 2 to 4 message signals, and obtain the Time-Division—Multiplexed waveform and then perform de-multiplexing and get back the original message signals (represent the signal in time domain and frequency domain at various stages).
5. Consider 24 message signals, and obtain the T1 Carrier bit stream. (represent the signal in time domain and frequency domain at various stages).
6. Consider the irreducible polynomial of order N (3 or 4), and obtain the 2AN-1 Codes, for the CDMA system. Build the Spread Spectrum modulation using any one of the valid codes.
7. To verify the correlation properties of the codes developed for the CDMA.
8. To build the BPSK-OFDM modulated waveform for binary input data stream, and recover the message signals from the modulated waveform.
9. To build the QPSK—OFDM modulated waveform for binary input data stream, and recover the message signals fiom the modulated waveform.
10. To build the GMSK modulated waveform for binary input data stream, and recover the message signals from the modulated waveform.
Course outcomes: After the completion of this laborator chourse,The students will be able to:
1. Use simulation tools to demonstrate various aspects of the communication process.2. Demonstrate the modulation/demodulation based on BPSK/QPSK-OFDM, GMSK, TDM.
3. Analyze the properties/performance of CDMA-based codes.
4. Model the T1 Carrier bitstream.
5. Develop codes to characterize and compute the parameters of different channel models of wireless networks.
Conduct of Practical Examination:
- All laboratory experiments are to be included for practical examination.
- Strictly follow the instructions as printed on the cover page of answer script for breakup of marks.
- Change of experiment is allowed only once and Marks allotted to the procedure part to be made zero.
