Appendix_B

This program simulation is used to simulate the performance of Mary noncoherent FSK modulation (BFSK,4FSK,8FSK and 16FSK) in AWGN channel for SNRdB change from 0 to 12 dB and print the modulation type ,SNRdB and Bit error rate for each steps. finally the program is plot the BER versus SNRdB for four type of noncoherent FSK modulation
