Hello Guys
I'm creating a customized block in the GNU Radio framework using
python that takes in a number of input items and once that number of
input items surpasses a certain number, 1024 of the input items are
taken and stored into an array, and then those items are converted to dB
and lastly compared to a threshold value, 5 in this case. If any of the
values are greater than the threshold value, a message is printed
indicating a signal is present, and if none of the values are greater
than 5, this is indicated with a message stating "No signal is present".
In the flow graph attached, I'm using a cosine source and a gaussian noise source to test my block in two different scenarios.
