Hi there,
before delving into the details of the OFDM implementation in GNURAdio I
wanted to ask a high-level question:
What is the method used for initial timing/frequency acquisition?
Is there one or two training OFDM symbols that precede the transmission
of data? and how many OFDM data symbols are following? Is this number
determined by the first training symbols or is it fixed?
Also, my understanding is that each data OFDM symbol has pilot tones for
continuous frequency/timing tracking, right?
Thanks
Achilleas
