Hi,I think it's TDMA/FDMA, not spread spectrum. Each channel is about 30KHz.Best regards,Cheng ChiOn Wed, Jan 29, 2014 at 10:17 AM, Marcus D.

I am trying to collect signal from Thuraya-3. Here is the setup I used:- USRP N210 + WBX- LNA with 30dB gain (ZHL-1217MLN)
- Iridium Antenna (I don't have specific antenna for Thuraya right now. Since Iridium and Thuraya frequency bands are quite close, I suppose it would work more or less)
Center frequency: 1530MHzSampling rate: 10MHz
From the spectrum (attached), I can see the Inmarsat signal, but no sign of Thuraya signal. Anyone has suggestion about how to receive the thuraya signal?
Best regards,Cheng Chi
