Gr-plc

GNU Radio blocks and library for IEEE1901/HomePlug-like communication.

See project page: http://roeebar.github.io/gr-plc/

Installation

Prerequisites

GNU Radio

The project was developed for GNU Radio 3.7.9.

There are several ways to install GNU Radio. The fastest route is using GNU Radio Live on a USB drive with Persistence. A nice tutorial can be found here: http://gnuradio.org/blog/using-gnu-radio-live-sdr-environment/

IT++

gr-plc library depends on IT++ library for the turbo encoder/decoder. GNU Radio Live installation already includes this library. Otherwise, see IT++ installation documentation.

Build and Install

For building and installing gr-plc run the following:

git clone git://github.com/roeebar/gr-plc.git
cd gr-plc
mkdir build  
cd build  
cmake ../  
make  
sudo make install  
sudo ldconfig  

Install PHY block

The physical layer is encapsulated in a hierarchical block to allow for a clearer transceiver structure in GNU Radio Companion. This hierarchical block is not included in the installation process. You have to open /examples/phy_hier.grc with GNU Radio Companion and build it. This will install the block in ~/.grc_gnuradio/.

Check message port connections

Sometime the connections between the message ports (the gray ones in GNU Radio Companion) break. Therefore, please open the flow graphs and assert that everything is connected. It should be pretty obvious how the blocks are supposed to be wired.

Notes

• To disable thread priority UHD warning, add the following to /etc/security/limits.conf

    @<group> - rtprio 99  
  

  Where <group> should be replaced with the user group

• For a 'debug' build, replace the cmake above with:

    cmake ../ -DCMAKE_BUILD_TYPE="Debug"
