You can upload your own block codes. Create a .txt file containing a generator matrix. This file may contain only bits, commas and line breaks to structure your matrix and to ensure readability. Columns need to be comma separated and rows are separated by line breaks. An example is shown on the right.


After selecting your local .txt file, click update. A trellis based on your code example will be created and shown. You can download a file containing TikZ Code of the trellis diagramm and change it to meet your requirements, if necessary.


Additionaly you can upload a received vector to be decoded. Your vector should be in a separate file and its bits should be comma separated. You can see an example sequenence on the right. The decoding process will be shown in an animated diagram and you can download the corresponding TikZ Code.
