Python Bindings for Coded Modulation Library https://github.com/wvu-wcrl/CML

This project aims to provide bindings to the encoders and decoders of the CML for Python. Currently supported functions:

Keywords: Python, channel coding, coding, LDPC, convolutional code, signal processing, coded modulation library.

• ldpc.InitializeWiMaxLDPC - create generator and decoder matrices for WiMax-Compatible LDPC codes
• ldpc.Encode - Encode payload bits with LDPC code
• lpdc.MpDecode - Soft-in-soft-out decoding of LDPC codes

• convolutional.Encode - encode bit sequence with given generator polynomial
• convolutional.SisoDecode - soft-in-soft-out (BCJR) decode of convolutional code

Feel free to add more bindings. Check the files under test/, how the functions are to be called.

• Prerequisites:
  • Swig
  • Numpy, Scipy
  • a working C++11 compliant compiler
• just type python setup.py build. This will build the extension using swig.
• then run python -m unittest discover to run the automated tests to see if it compiled correctly.

Currently tested under Windows with Python-2.7.9, using Visual Studio 2013 compiler backend.
