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 ________________________________ Od: Müller, Marcus (CEL) <muel...@kit.edu> Odesláno: pondělí 17. prosince 2018 12:51:10 Komu: discuss-gnuradio@gnu.org; Horký Petr Předmět: Re: [Discuss-gnuradio] Wifi signal -pulse train+bspk 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!
