C program to calculate the BER performance of BPSK modulation in an AWGN channel. The program takes the file "BPSK" containing voltage levels and passes it in an AWGN channel with a given SNR. The received message is then Hard decision decoded and the bit error rate is calculated. The BER over different SNR is calculated. THe output values can be used to draw a BER vs SNR(dB) curve.
