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!
