I have to agree with you, and I don't understand what's going on. It looks like the magnitude of the taps should be 1.0, even if there's a phase offset. On 01/11/2018 03:53 PM, edwin wrote: Hi Jeff, Thanks for the reply. What you said about the noise makes sense. However, even if I turn the

Hi Jeff, Thanks for the reply. What you said about the noise makes sense. However, even if I turn the noise off, I still get the weired taps: Offset: 2112  Source: n/a Key: ofdm_sync_chan_taps   Value: #[(0,0) (0,0) (0,0) (0,0) (0,0) (0,0) (35.5567,-53.2143) (-6.27313,-63.6921)

[Discuss-gnuradio] GNURadio FFT Plot and UBX Maximum Input Power
