Hello everyone, I was trying to understand how the synchronization in gr-ieee802-11 actually works and went through:
Bastian Bloessl, Michele Segata, Christoph Sommer and Falko Dressler, "An IEEE 802.11a/g/p OFDM Receiver for GNU Radio" However, it seems that the Short Sync and many other blocks have developed further since then. >From what I understand, the current sync_short.cc does the following: 1) searches for the peak normalized correlator o/p and compares with the set threshold 2) as enough number of simultaneous peaks are detected in correlator o/p, it moves onto the copy stage Here is where my doubt lies. Does the block keep looking for new frames while the old one is being copied? Also, what is MIN_GAP's function in the code and how is its value decided upon? Could you please clear up these doubts a little? Bests, Nikita Airee
