Alpha is the pole placement in the single pole IIR filter, used to filter the signal before it is compared with the threshold. Details may be found in gnuradio/gnuradio-core/src/lib/filter/gr_single_pole_iir_filter_xx.ccHi all I had a problem with tunnel.py, but changing threshold from 30dB to 50dB it was solved, now I'm reading receive_path.py in carrier sensing blocks are defined alpha=0.001 and thres=30 for use with gr.probe_avg_mag_sqrd_cf, please can somebody tell me what is alpha value and why is set to 0.001?
