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 ...

Low-Density Parity-Check (LDPC) codes represent a class of error-correcting codes that have fundamentally reshaped the field of digital communications. With their inherently sparse parity-check ...

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 ...

Traditional cyclic redundancy checking (CRC) techniques have emerged as a strong solution for handling errors in emergingwireless and DSL designs. Cyclic redundancy ...
