Ah OK, I see, taking the samples from the end is indeed stupid -.-
Thanks for your explanation!

Hi Bastian,

just a quick follow-up: Did you have any problems with the rolloff
spectrum, or what caused you to change the code?
I checked the output, and it seemed correct--although I didn't
have the theoretical values here to compare the results to those.

I am currently measuring the packet error rate of a transmitter that uses the Cyclic Prefixer block. I experienced some strange effects that I could not explain and thus looked at all blocks again. Somehow I thought rolloff -> use samples from the end which is stupid as you pointed out :)
So no, everything seams to work now.

Thanks for your help!
