simulate the hamming code with bit error rate

In this project we simulated BPSK, QPSK and 8 QAM each with Rectangular pulse shaping and Square root raised cosine. Also we applied Hamming code (7,4) and generated the Bit Error Rate (BER) performance graphs. The number of coefficients for the FIR Raised cosine filter was found to be 25.Usiing this filter it was observed that dB loss at BER of 10^-5 was less than0.5dB for BPSK and QPSK and it was exceeded to 1.5dB for 8-QAM.The coded performance was also simulated and found that coding gain was 0.2dB for BPSK/QPSK. Whereas, it was 0dB for QAM at BER of 10^-5.
