Richard Hamming's elegant solution to unreliable communication turns a simple parity trick into a self-correcting system, revealing how redundancy can be structured rather than brute-forced. This is ...

RS codes can be shown to be an LDPC, for instance. Only a few years earlier, a similar FEC, the Turbo Codes were introduced. These codes also came very close to Shannon’s limit. The drawback is they ...

The use of parity bits is a common method of detecting errors in data transmission and storage. Before looking at the use of parity bits in RAID, let's look more ...

Error detecting and correcting codes are based on significant distance between two bit strings in terms of the number of bits that have to alter to get from the first ...
