I am confused about the new terminology 'oversampling' I have encountered very recently. To explain it better, I am going to use numerical examples. Now let's assume I am using a BPSK modulator and my symbol period is 1 second. To digitize and process this using MATLAB or Python, what I was doing was to discretize the signal with 100. (Using np.repeat() or repmat to information bit sequence). My questions are:
1) Is this value (100) the oversampling factor?
2) Is this discretization value of mine, is the ratio between symbol duration times sampling frequency of the system ?
3) If the ratio that I mentioned earlier is not what oversampling is, can you explain or give me links for some kind of explanation? ( I found a lot about it but it made me even more confused due to the fact people are using upsampling and oversampling interchangeably, which I think is totally wrong)
Thanks in advance.
