Hi Jeon, in such a case, linking to the original file [1] including line number might be more helpful, as it gives more context. So, looking at this, it's taking the delayed input samples and copies them (offset-corrected) to the output, considering parts of the samples, x = ignore, o = copy, starting at the frame start: oooooooo|xx¦oooooo|xx¦oooooo|... 128 |16¦128-16|16¦128-16|... I'm not too familiar with 802.11p frames, but that looks like Basti's leaving out some pilots in between the data, probably only copying the preamble and data payload. But I could be wrong.
