bit eror rate

hello lets say i have this random bits bits= randint(1,1000)

and after few math functions i get x=(1,1000) how do i calculate and make a plot of the ber when i make this math function 10 times for 10 diffrents snr? thanks!

please, can I get the ApplySNR function?

ApplySNR is your own function for transforming the bits according to the given SNR. For example you might use awgn() and then make a decision about the result.

Answer 1

[Walter Roberson]

SNR = [1, 2, 5, ... whatever]
N = length(SNR);
ber = zeros(N,1);
for K = 1:N
  x = ApplySNR(bits, SNR(K));
  ber(K) = mean(x ~= bits);
end
plot(SNR, ber);

Where ApplySNR is your function for transforming the bits according to the given SNR.
