ADIDAS

Advanced Development for Internet where all Data Arrives Safely.

Simple handling of data transmission corruption.

This implementation will only work when there is no more than onecorrupted bit per byte.

This repository contains 3 sub-programs:

encode

This program is responsible for encoding an input file.

For every byte from the inputfile, two bytes are generated and placed in the output file.

Byte 1 has the 4 databits + 3 parity bits of high nibble.

Byte 2 has the 4 databits + 3 parity bits of low nibble.

The program prints at the end how many characters are read and how many bytes are encoded.

Use: encode inputfile outputfile

channel

This program is responsible for adding noise bits to the data.

For all bytes one random bit is flipped.

The program prints at the end how many bytes are read, how many bytes are encoded and how often each bit is flipped.

Use: channel inputfile outputfile

decode

This program is responsible for error correction (the decoding) on a file.

The program prints at the end how many bytes are read and how many characters are decoded.

Use: decode inputfile outputfile
