[Discuss-gnuradio] Cyclic Prefixer Rolloff Samples

[Bastian Bloessl]

Hi,

I wonder why the OFDM Cyclic Prefixer uses the samples at the beginning 
of the symbol to calculate the roll off. I would have expected that the 
samples from the end of the previous symbol are used. So something like 
this:

But since also the unit test expects the samples from the start of the 
symbol I might get the concept totally wrong.

Best,
Bastian
