Forward Error Correction

Tools used:

• Pycharm (Python IDE)
• Online image comparison tool available here.

Project Description:

This implementation is a result of a university course:
"Reliability and Diagnostics of Digital Systems"

The group was to provide an implementation of the following:

• BSC nad Gilbert channels
• Error correction codes: TMR, Hamming(8,4), Reed-Solomon
• Interlacing as a tool to break up big chunks of error bits into smaller groups

The outline of a main algorithm of result checking:

1. Prepare the input file.
2. Send it through a selected channel.
3. Use a selected correction code to retrieve the original image.
4. Compare the results with an image comparison tool.

Each channel is characterized by a set of attributes:

• Binary Symetric Channel:
  • p - Probability of error occurence
• Gilbert:
  • p_gb - Probability of state switching: good -> bad
  • p_bg - Probability of state switching: bad -> good

Sample results of error correction are stored in the Images folder.

Imported libraries are stated in a generated requirements.txt file.
