Hi everyone, there's new stuff on our CGRAN repositories you might enjoy.
* Channel Coding Toolbox We've created a new toolbox for channel coding stuff. https://www.cgran.org/wiki/chancoding It includes some simple bit-based channel models (a standard BSC and Markov-modeled BC) and generic block interleavers. The most interesting part is definitely an implementation of binary Reed-Muller codes. These codes have some uses; among others, sub-sets of these codes can be used to bound the PAPR of OFDM signals (pre-set code is available). One of our students (Nico Otterbach) implemented these codes as part of his Bachelor's degree. A very well-written thesis with a nice introduction to RM-codes is in the repository, unfortunately (for most of you) it's in German. * More Spectral Estimation Codes! https://www.cgran.org/wiki/SpecEst As part of another students project, spectral estimation based on ESPRIT and MUSIC is now part of of the Spectral Estimation Toolbox (this means we now have more spectral estimators implemented than Matlab does :-). I'd like to thank Manuel Fuhr and Moritz Fischer for doing the hard coding work. This toolbox now has some cool elements: for one, it includes Fortran code, which is quite an achievement by itself. Next, Moritz has ported the whole thing to CMake. If you're interested to see how this can work for complicated out-of-tree modules, have a peek at the code! Both projects include Doxygen-generated documentation and GRC bindings for most blocks. Besides announcing this, I'd like to encourage the use of GNU Radio stuff for university credits. Obviously, we've had a lot of good experiences with this, but it's also a good deal for the students: fundamental understanding of signal processing requires implementation (at least that's my opinion), and it is very satisfying to have a working, reusable product when finishing such a project.
