Hello.
Has anyone an idea how to demodulate more than one channel per time while using an USRP or FCD? The provided bandwidth is big enough. But how the split the 25kHz channels into seperate streams? Any idea is welcome.
Thx
Martin
Hi Martin, i have the same problem. In my area there is only a tetra network, but there are a lot of BS, so from my house i receive 5 different frequencies of the same network.
I'm developing a little mod for the qthid that analyze if on a frequency there is traffic, and if not, switch to the next frequency, and continue in loop until on a frequency detect traffic.
When i finish it, i share with us.
Excuse for my bad english but i'm italian...

Hi, Does anyone have a sampled TETRA file you can share with us? It would be really useful if someone with a USRP save the sampled file and share with us.
If you need space, I can offer free space on my personal or company site (up to 2G).
Thanks in advance, Farhad

Hi Sylvain,
Thanks, I know that one, but I need a larger file if possible.
Here in France where I live we have no TETRA networks available and I want to test my receiver with a real sample to make sure it works properly.
Best regards, Farhad

the sample is generate with the receiver, whit a sample you can test the decoding software but not the receiver.
