*Demonstrate convolutional encoding and decoding

*Simulate BER for QPSK and BPSK, plot and then **compare the result with the theoretical value.

*compare SER of the Rake and ML.

– Symbols are taken randomly from QPSK.

– Run the simulation for different SNR until at least

50 symbol errors are found

– Plot the figure with x-coordinate in SNR (dB) and ycoordinate

in SER. (Matlab function semilogy)
