I just got it to go to -18 dB at a delay of 24. I apologize, my previous email was premature. Let me play around a bit more before emailing. ________________________________ From: Matthew J.

Hello, I don't have QT gui so I had to convert to WX blocks (how do I install QT?). I cannot get the BER to change appreciably, no matter what delay I set. The best I can get it to is only about -1 dB. I will keep playing with it. ________________________________ From: Achilleas Anastasopoulos [anas...@umich.edu] Sent: Monday, November 19, 2018 5:37 PM To: Matthew J. Brandsema; Discuss-gnuradio@gnu.org Subject: Re: [Discuss-gnuradio] Packet Decoder Breaking when adding noise I attach a simple grc file that works for me. Using the delay10/delay sliders try to align the input/output bit stream. (in this example this happens at delay=12, but it may be different for you...) Then play with the noise variance; you will see the BER changing slowly as you go around values = -6,-5,-4 let me know if this works for you, Achilleas
