When sensitive data like banking information is transmitted, even a single flipped bit can corrupt the entire message. This video explores how engineers solve that problem using error correction codes ...

Last month I showed how coding and error correction allows next-generation broadcast technologies such as DVB-T2 and DVB-NGH to achieve performance very close to the ...

Computers employ a variety of schemes to check whether a chunk of digital information–transmitted as a message, stored in a database, or functioning as a set of instructions–remains error-free. Such ...

For communication designers, especially those in the networking and wireless field, the Shannon limit can be seen as the Holy Grail. And, since being first defined in ...

Low-Density Parity-Check (LDPC) codes represent a pivotal advancement in error‐correcting technology, enabling robust data transmission across noisy communication channels. Their decoding methods, ...

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 ...
