-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Simon,
I recommend using QT GUIs. WX GUI will be removed eventually. 'stream to streams' does not duplicate samples. In your case the first sample goes to output 0 and the second sample goes to output 1. <repeat pattern> For AWGN you should observe another noise for in your FFT plot. Your received signal is not a perfect AWGN signal. e.g. your dip is probably some 1/f noise caused by some analog part in your USRP. Have a look at the unprocessed samples form the USRP source. happy hacking Johannes On 04.08.2015 15:07, Simon Olvhammar wrote: > Hi, > > I'm seeing some strange behaviour in Gnuradio that i cannot > explain.
