Re: [Discuss-gnuradio] IEEE 802.11 Transceiver Module - Timing offset at receiver side

[Qurat-Ul-Ann Akbar]

Thank you for the explanation. Can you tell me which antennas did you use for your experiments when you wrote your paper? Because I think a major problem with my receiver is a very low SNR because everything works fine with simulations. Currently I am using Vert 2450 antenna with my USRP N210.

Hello,

How is the timing offset being handled in the 802.11 module. I see that the sync_long block does frequency offset correction and the frame_equalizer block does the phase correction but I dont understand where is the timing offset being handled. Can anyone tell me which algorithm is being used to do that?

The Sync Long block correlates the signal with the known pattern of the long preamble to derive how the FFTs have to be aligned in time.
