the file which is uploaded is the uncoded systtem technique which we simulated. it gives the BER vs Snr curve.The un-coded system is simulated is by using randomly generated numbers and it s passed over the AWGN channel.the output of the matlab file clearly shows that the BER value of 10^-1 only is reached at a SNR of 20 db in the uncoded system. the file also has the simulated graph of the uncoded system.-the file which is uploaded is the uncoded systtem technique which we simulated. it gives the BER vs Snr curve.The un-coded system is simulated is by using randomly generated numbers and it s passed over the AWGN channel.the output of the matlab file clearly shows that the BER value of 10^-1 only is reached at a SNR of 20 db in the uncoded system.　the file also has the simulated graph of the uncoded system.
