How to resample a signal by a fraction
60 visualizaciones (últimos 30 días)
I have the time-domain received signal v(t) and I want to re-sample it at as v(t/(1+a)), where a is not an integer and it is in the order of ~10^-3. How can I do that in MATLAB, since the resample function requires that both P and Q be integer?

I suggest you reciprocate your a variable and round it to the nearest integer. You then just need to make sure you get the arguments the correct way in the resample function.
y = resample(x,p,q) resamples the sequence in vector x at p/q times the original sampling rate

Is this any help?
% SincResample returns the data convolved with a set of time-shifted windowed sinc functions, one for each of the samples [1..size(x,1)] in the input signal.
