I can't wrap my head around why fft transform of complex signal produces a complex output. After all the output reflects the amount of energy per frequency bin and frequency bins and energy are both real numbers, no?I'm trying to write a python script to analyze the energy across frequency bins but
Thank you this helps a lot. I'll place my complex to mag block directly at the fft output. Then I can send that to a vector sink and review my bin data. [Brad Hein]-Original Message-From: wa1...@wa1hco.netTo: discuss-gnuradio@gnu.orgCc: Sent: 2014-10-11 17:59:24 GMTSubject: Re: [Discuss-gnu
Can you perform the alignment prior to the but comparison stage? This would simplify the comparison so that it can focus on BER alone and no alignment tasks. It would also address the following:Another issue that may arise if the bits streams are not aligned during comparison is that as you slide t
A challenge that I am encountering recently when building flow graphs is with
upsampling and downsampling and getting the sample rate where I need it.
Sometimes I have rate mismatches and don't know a good way to take measurements
with grc so I can troubleshoot. Is there a nifty way to measure t
Take a look at netstat -s and see if that helps isolate if or where
packet loss is occurring. For example in the udp: section there are statistics
for total datagrams tx/rx along with dropped, bad checksums, etc. UDP has no retransmission feature built in so bad checksums and bad packets
get dro
Make sure on the server you're binding to 0.0.0.0 (use netstat -na to
confirm).TCP may help over UDP unless the dropped packets were
caused by congestion, which seems like a likely culprit. [Brad Hein]Make sure on the server you're binding to 0.0.0.0 (use netstat -na to confirm).TCP may help over
