The gr-lte project is an Open Source Software Package which aims to provide a GNU Radio LTE Receiver to receive, synchronize and decode LTE signals. Its development was focused on modularity. This makes the project easy to extend and reuse its blocks.

This project was initiated as a Bachelor thesis at the Communication Engineering Lab (CEL) at the Karlsruhe Institute of Technology (KIT), Germany, http://www.cel.kit.edu.

• GR 3.6.5.1
  • message passing API is necessary
  • all the latest bug fixes
  • project uses GR 3.6 API
• MATLAB (R2011b tested)
  • for .m-files
  • If you want, have a look at the m-files
  • Python/Numpy/Scipy Code is supposed to replace the m-files

1. Get, build and install GNU Radio from http://www.gnuradio.org

2. Get gr-lte from github

3. Configure it using CMake
   Assuming you are already in the project folder
   cd code/
mkdir build
cp cmake_install.sh build/
cd build
./cmake_install.sh
   
   This will just run a little script to aid with project setup for Code::Blocks

4. run sudo make install
   make -jX where X is a number of choice (Often the number of cores available)
   sudo make install (make it available in GRC)

5. Have fun
   If everything runs without errors the -gr-lte blocks should be available in GRC

This project aims to provide a modular environment for an LTE downlink receiver. All blocks should be replacable. e.g. introduce a new channel estimator block with more advanced algorithms.
On the other hand it should be fairly easy to add new blocks to decode additional physical channels.
