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 ...

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 ...

Calculating an LDPC Note: the 3rd parity bit should be 0, not 1 LDPCs append a series of parity bits to a message. Usually the encoded stream is relatively long — 1024 bits would be a short message.

ECC adds multiple parity bits, though calculations are usually applied to complete words (typically 32 or 64 bits), not single bytes. Each ECC bit represents the parity of a different subset of the ...
