The aim of this project is, to provide a .Net implementation for encoding and decoding convolutional codes. The decoder is implemented using a Viterbi algorithm as described in the wiki book A Basic Convolutional Coding Example.
The project is still at it's beginnings, but there is a test program included, that can already encode and decode convolutional codes.
If you have any thoughts on the code or even a PR, please let me know.
var config = CodeConfig.Size3_7_5;
var input = "10110".ParseBools();
var encoder = new Encoder(config, terminateCode: false);
var output = encoder.Encode(input);
var viterbi = Viterbi.CreateWithHammingDistance(config);
var restored = viterbi.Solve(output);
Console.WriteLine("Configuration: " + config);
Console.WriteLine();
Console.WriteLine("Input: " + input.Format());
Console.WriteLine("Encoded: " + output.Format());
Console.WriteLine("Restored: " + restored.Format());
Console.WriteLine();This will produce:
Input: 10110
Encoded: 1110000101
Restored: 10110
The logic is written as a .Net Standard 2.0 dll and should be easy to reference from any project.
