I have a signal for which I know the OFDM burst length (from the autocorrelation function of the signal) T_burst
and the FFT size 1024 (by measuring the channel spacing) and the guard interval (128).
- How should sample such a signal for OFDM demodulation ?
- What is the ideal sample rate for that ?
- Is it
(1024+128)/T_burst
?
I plan to use GNU radio for demodulation, like this (this image is from IRC channel - credit to drmpeg):
