To apply window function on Wigner-Ville Distribution in Matlab

Question

We were thinking here how to create Hamming-64 window of overlap 64. It is done by

h = hamming(64);
h2 = hamming(38);
h = conv(h, h2);

Now,

Answer 1

Extension to lennon310's answer.

I run

data1 = conv(h,data);
[B,T,F] = tfrwv(data1, 1:length(data1), length(data1));

and then plot it with picture of no windowing

I know that the picture without windowing is proper, since I can see there 60 Hz horizontal line caused by the settings of the measurement system in MIT-BIH arrhythmia database. The patient is 68 years with old myocardii infarctum so the beats per second reaching 65 is proper with this method.

The picture with the implementation of my original version of hamming-64 is not proper. The person would not live long with such beats per minute.
