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!

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.

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.
