Transmitting binary 1's and 0's using different modulation schemes


#1

Hello everyone,

Is there a python script available in Gnu Radio in which you can supply
at
the input line a bunch of binary “1’s” and “0’s” and transmit them using
different modulation schemes such as dbpsk, gmsk, qpsk, etc…

Also, is there a receiver that can take the transmitted signal, reduce
it to
baseband and then collect it’s analog values using “gr.vector_sink_c()”?

Thanks

Hello everyone, Happy New Year!

Does anyone have a solution to this post yet?

Your help will be greatly appreciated. Thanks!

Neither of these scripts exist. Why don’t you write them?

Okay, I just wanted to make sure it wasn’t out there before I delved
into
it.

Thanks

i think you can modify the benchmark_tx.py code for transmitter and
benchmark_rx.py for receiver for this application :slight_smile:
