[Discuss-gnuradio] Phase locked loop

2015-03-16 Thread yee_yy1992
Hi, Currently I am doing my Final Year Project to develop a phase measurement using Phase Locked Loop theory. I am using USRP N210 for the hardware and I have installed Gnuradio Companion in Ubuntu 12.04 LTS (running in VMplayer). I have studied online that I can’t use companion to add and

[Discuss-gnuradio] Relative Path to File with File Sink/Source

2015-03-16 Thread Richard Bell
Easy question here. I'm trying to use a relative path with file sink/source. It errors out with can't open file. I'm assuming the path is relative to the location of the .grc file location. If the location of the .grc file was: /home/user1/proj1/devel/myfile.grc And a data file was here:

You're probably not running the script from where the .py is, but from where GRC started. Relative paths are relative to that folder. That means that if you run gnuradio-companion from your home directory (which is probably the default when you just open it from some menu), then paths are relative

Hi.. the existed costas loop only considers the phase of the received signal (for PSK techniques). But for QAM we have to consider both the magnitude and phase of the received signal. I want to use the same costas loop for QAM. where should I modify the C++ code? is that requires to modify the

The problem I have with absolute paths, is that I use Git, and when I clone a repo to a new computer, with different user names and directory structures, all the existing absolute paths will be broken. The only thing I can ensure is the structure of the Git repo will be the same. Thanks for

Re: [Discuss-gnuradio] Relative Path to File with File Sink/Source

Generally, you'd expect that someone with a file sink/source would either use absolute paths to ensure there's no ambiguity, or would like to see the paths behave relative to the current working directory of the process, which is what I'd expect from a unix program. However, you can add an import
