fourier - Phase information


I am quite new to MATLAB and I am currently trying to do some Fourier synthesis. In order to do the Fourier synthesis I need the phase information of the harmonics as a fraction of the period of the fundamental frequency. I am a bit lost on how to do this. Also I am trying to do a Fourier synthesis using the equation


$$y[i] = y[i-1] + p[j]\cdot \cos\left[2\pi f[j]\left(t- \dfrac{\gamma[j]}{f[1]}\right)\right]$$


Is this correct?

I have a question about matched filtering. Does the matched filter maximise the SNR at the moment of decision only? As far as I understand, ...
