Which More Complex: Integration or FFT?

[David83]

Hello all,

I have a practical question: I have a received block of length K symbols. Now, which is more complex, to take the integration from kTs to (k+1)Ts for k=0,1,...,K-1, or take the K-point FFT for all symbols?

Thanks

Any one? If I am asking in the wrong forum, please direct me to the appropriate one.

This is an "analog design" forum, it would be better posted at the "digital signal processing" forum.

OK, thanks.
