Re: [Discuss-gnuradio] Wifi signal -pulse train+bspk

[Horký Petr]

Hello,
We are trying to take control over drone. 

The drone starts for example  at 2,4 GHz and has some pulse width, and pulse repetition frequency we know. 

Pulse1: at start of pulse there is 2,4GHz carrier to synchronize and then BSPK data (two numbers in binary)
Pulse2: carrier 2,4GHz + BPSK
Pulse3: carrier 2,45GHz + BPSK
Pulse4: carrier 2,45GHz+BPSK
Pulse 5: carrier 2,5Ghz +BPSK ....and so on
After 12 pulses it starts again at 2,4GHz.

So I have pulse width, pulse repetition frequency, carrier frequency (which hops after 2 pulses), and BPSK (16 bits I think).
I hope that now it is a little bit more understandable. :) In case it is not a will do my best to describe it better. 
Thank you for help,

Regards,

Petr

Hi Horký,

could you give us a bit more context? The signal you're describing
sounds like a single-carrier system, but (modern) WiFi is an OFDM
system, so I'm not sure what you really want to achieve?
Maybe paint the bigger picture of why you need this!

Best regards,
Marcus
