AWGN channel. Uses a file called BPSK (containing BPSK voltage levels) and adds gaussian noise to it. The noise is generated by box muller equation. Note: BPSK file was generated from BPSK modulator source: BPSK.c

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 th
