[Discuss-gnuradio] GR-Inspector Installation problems

Hi all, I am attempting to install GR-Inspector for use with GNU Radio on Kali O/S. I have followed the instructions on https://github.com/gnuradio/gr-inspector, and followed the commands: git clone g...@github.com:gnuradio/gr-inspector.git cd gr-inspector mkdir build cd build cmake .. make -j4 sud

Re: [Discuss-gnuradio] Clock recovery without change of phase

2017-06-14 Thread Federico 'Larroca' La Rocca
Hi, I'm not sure if I understood correctly your question, but clock recovery (such as MM or Polyphase clock sync) takes the incoming signal and by default outputs a sample every $T_s$ seconds (symbol time) but at the point where the eye is widest (and thus it interpolates as needed). Once it conver

I think I found out the possible source of problem. Toda I found out the following issues with “Packet Encoder/Decoder” blocks. I replaced the TUNTAP PDU block with a Wav File Source and Audio Sink blocks at the transmitter and receiver, respectively. I noticed that always the receiver side mu

[Discuss-gnuradio] Clock recovery without change of phase

2017-06-14 Thread George Vardakis
Hi all, I need to perform clock recovery on a signal without constantly changing its phase. I think that the clock recovery block in Gnuradio does exactly that in order to maximize the energy of the signal. Is there any other way that does not tamper with the signal phase? Thanks! ___

Re: [Discuss-gnuradio] Signal distorted when using concurrently two USRP B210 devices

2017-06-14 Thread George Vardakis
After all this might be an expected behavior. Since the devices have different clocks, they sample the medium at different time instances,leading to this "distortion" of the signal. That's why this only happens when the one USRP transmits and the other receives, and not when the same usrp transmits

I don't know exactly what you mean by bringing up interfaces. Let's say I assign 192.168.200.1 to PC1. For sure I can ping 192.168.200.1 on PC1. But from PC2, this destination is unreachable. I don't know what the issue could be. Since. I'm just a Linux user (not an expert) I have no clue where
