Error correcting codes
Example: Code consisting of 4 code words
- 0000000000, 0000011111, 1111100000, 1111111111
- Code has distance 5. Therefore double errors can be corrected
- If 0000000111 arrives, the receiver knows that the original must have been 0000011111.
- If triple error changes 0000000000 into 0000000111 then by a minimum distance approach we will not correct the code word.
