List of Experiments:
1. Simulate a wired communication system in which information signal is sent out over an AWGN channel. Assuming BPSK modulation plot BER vrs SNR curve in Matlab. Compare the simulate and theoretical curve.
2. Simulate a wired communication system in which information signal is sent out over an AWGN channel. Assuming QPSK and 8PSK modulation plot BER vrs SNR curve in Matlab. Compare the BER performance of different digital modulation schemes. Compare the simulate and theoretical curves.
3. Simulate a following long term propagation models (with shadowing and clutter factor) for wireless communication: a). Friis free space model b). Two ray model c). Okumura Hata model. Observe these models for change in frequency and distance.
4. Simulate power delay profile for a wireless communication system. Compute mean access delay and relate coherence bandwidth for different power delay profiles.
5. Simulate a wireless communication system in which information signal is sent out over an AWGN channel with flat fading. Assuming BPSK modulation, plot BER vrs SNR curve in Matlab. Compare performance with wired channel. Also compare the simulate and theoretical curve.
6. Simulate a wireless communication system in which information signal is sent out over an AWGN channel with flat fading. Assuming QPSK, 8PSK modulation, plot BER vrs SNR curve in Matlab. Compare performance with wired channel. Also compare the simulate and theoretical curve.
7. Simulate a wireless communication system in which information signal is sent out over an AWGN channel with flat fading. Assume one transmit antenna and multiple receive antenna with BPSK modulate transmit symbols. Assuming Selection combining equal gain combining and maximal ration combining, plot BER vrs SNR curve in Matlab. Compare the simulate and theoretical curve. Compare the performance when there is one two three receive antennas. (make sure power received remains same in all the cases) .
8. Simulate a wireless communication system in which information signal is sent out over an AWGN channel with flat fading. Assume multiple transmit antenna and single receive antenna with BPSK modulate transmit symbols. Assuming no channel state information and channel state information at transmitter, plot BER vrs SNR curve in Matlab. Compare the simulate and theoretical curve. Compare the performance when there is one two three transmit antennas. (make sure total power transmitted remains same in all the cases)
