Hi guys,
I have check the 802.11 standard before. It said the coase freq. estimation is done in short preamble, and the fine freq. estimation is done in long premable. However, to my best knowledge, gnuradio only uses one preamble for synchronization. So how are these two freq. estimation works done in one preamble. BTW, can anyone tell me the exact different between coase one and fine one? Are they both related to the FFT bin aligning?
