PyTurbo

A simple implementation of turbo codes in Python.

This project has not been optimized for speed, and only implements a simple rate 1/3 code with no puncturing. I might make it more generic, or implement an optimized version in C, but this package should really only serve as a reference implementation. It was created for a short technical blog post on my website.

About

Turbo codes are a class of error correction codes that are used in cellular communication standards (e.g. 3GPP LTE) and deep space communications. With long enough codes, they can approach the theoretical capacity of a channel, and provide excellent performance for their decoding complexity.

Getting Started

Take a look at the examples folder for visualizations and test inputs to the encoder and decoder.

To test things out quickly, install venv:

$ [sudo] apt install python3-venv
$ python3 -m venv pyvm
$ source pyvm/bin/activate

Then, execute the following commands:

$ git clone https://github.com/DaulPavid/pyturbo.git
$ cd pyturbo
$ python setup.py install
$ cd examples
