Hi,
I need to implement Poyphase FFT code in Matlab, If any one can provide me with code nothing better than that.
From net search I found out that Polyphase FFT is a channelization technique.
Please refer to link below:
**broken link removed**
In this link refer to Figure 3.9 (Polyphase FFT channelizer), actually I am not able to understand
1) what is purpose of FFT block in it as once channels are separated why do we need to take FFT of it, is it just for analysis purpose?
2) SRC block is before filter- If one downsample the signal first then it would create aliasing.
Any help would be appreciated
Thanks
