I have two scripts I am running, the ofdm_v1_tx_freq_test.py and the RX
version of it (see flow graph images and attached transmitter Python
script). I am transmitting a sinusoid using OFDM modulation over the
it works perfectly.
I have made an alteration to the transmitter script by adding a
change function that goes off every 2.5 seconds. The frequency will
inclemently go up 1 MHz 20 times before going back to the default. That
code works; what I want to do now is to cease the sinusoid broadcast at
every 2.5 seconds so I can transmit the new frequency to the receiver
before I change it. I think I can figure that part out, I may just use
another vector source with the new frequency and have transmit five
Probably use another flow graph to implement it. If there is a better
to do, I am open for ideas.
Now for my question: after receiving this new frequency on the RX side,
do I get my script to read this data and use it to change frequencies? I
have a feeling that this may be simple to do but I am at a loss in
Please note, this is more of a proof of concept work, so there is a
why I do not have identical frequency change functions in both TX and
the goal down the road is to get some DSA capabilities.
