Hey there everyone! I'm actually right now researching about ofdm based realization to efficiently estimate the doppler shift and I've kinda run into a block In the typical block diagram there's a IFFT/FFT block,I've read on many forums but I'm unable to determine the significance of the said block Also,if its possible could anyone help me understand why actually circular convolution is better ...
