Hello everyone, I am trying to implement a bandwidth segmentizer (cutting a given bandwidth into smaller channels) and energy detector using GNU Radio, as schematically shown here below, but I am experiencing some trouble.[cid:8fb1dd8a-c703-4b4a-8537-486f9afd71d1] More precisely, to achieve the desired result, I have tried to implement two python blocks, given in the attached archive, in files "compute_average_power.py" and "custom_thres.py". The goal of those blocks is to compute the average power contained in all the channels (compute_average_power.py), and feed that computed value to a self-made threshold block (custom_thres.py). So far, the implementation does not work. I have already learned in this post<https://dsp.stackexchange.com/questions/81858/problem-to-extract-value-from-complex-to-mag-squared-gnuradio-block> thanks to Markus Müller that using np.mean (where np is short for numpy) is bad because it depends on the length of input_items. I have however not been able to reach the desired result. Can someone help me out ?
Thank you, have a nice day, Alex P. S. : the whole, complete, code is given in the attached archive, in the "bw_segmentizer.py" file.
