Hi, here are some analog modulations. Because i can't upload the .grc file i will upload images The way in which I have done the modulations has been with its...
GNU radio already provides the necessary blocks for FM modulation and demodulation, in my case, I have used the WBFM transmit block, the output of this block already offers the...
By the way are you going to use two BladeRF (one to transmit and one to receive or are you going to use only one as transmitter and receiver?
I say this because I have commented on a problem about using 2 bladerf it will probably happen to you too. https://github.com/Nuand/bladeRF/issues/875
Make sure that the tone you use as a source has a frequency of 11000Hz and fs = 22050, with this you will not have to modify any other parameters....
I guess for your project this should not be a big problem.
You should sample the message at least twice the maximum frequency of the signal, after this you should interpolate your signal, that is, increase the sample frequency and adapt it...
Then in reception you must decimate your received signal, that is, reduce your sampling frequency again to recover your original signal and be able to adapt it to your sound...
Can you send a picture?
Hello, I am currently quite saturated with a project, but maybe I can help, the first error I see is a receiver-transmitter scheme, I mean it would be better to...
