Experiments

Hardware Experiments

1 Generation and demodulation of the Amplitude Shift Keying signal.

2 Generation and demodulation of the Phase Shift Keying signal.

3 Generation and demodulation of the Frequency Shift Keying signal.

4 Generation of DPSK signal and detection of data using DPSK transmitter and receiver.

Simulation Experiments (Use MUKU:GO / MATLAB / Scilab /LabVIEW or any other suitable software)

5 Gram-Schmidt Orthogonalization: To find orthogonal basis vectors for the given set of vectors and plot the orthonormal vectors.

6 Simulation of binary baseband signals using a rectangular pulse and estimate the BER for AWGN channel

using matched filter receiver.

7 Perform the QPSK Modulation and demodulation. Display the signal and its constellation.

8 Generate 16-QAM Modulation and obtain the QAM constellation.

9 Encoding and Decoding of Huffman code.

10 Encoding and Decoding of binary data using a Hamming code.

11 For a given data, use CRC-CCITT polynomial to obtain the CRC code. Verify for the cases, a) Without error

b) With error

12 Encoding and Decoding of Convolution code
