Re: [Discuss-gnuradio] Packet Decoder Breaking when adding noise

[Matthew J. Brandsema]

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.

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,
