hii
i want to normalise the desired signal( to 1db) which is signal with awgn noise of 20db
following is the code
t = 1000;
s = randn(1,t);
M = 1000;
%generate noise
lamda = 0.1;
K = 2;
s = [ 0 0 0 0 0 0 0 0 s];
d = zeros(size(s));
i = 9:length(s);
x(i) = 0.35*s(i) + s(i-1) +0.35*s(i-2);
d(i) = x(i) +0.2*x(i-8)-0.7*d(i-1);
d = awgn(d,20,'measured');
how do i normalize d's power to 1 db
thanks
