Majority Vote ECC

A method for fixing ECC by finding the most common similarities between several sent messages. Can only fix 1-bit of error.

Process

• Alice are sent in triplets. $010\to 000,111,000$
• If an error occurs, we can see it on Bob’s end ($000,101,000$) Note that $101$ is not in triplets, we fix this by seeing that $1$ is the majority item

Flaws

• This method fails if 2 bits fail, $000,111,000\to 000,001,000$ is not recoverable!
