Noise from the ambient environment can introduce errors into the data during digital data transmissions. This noise can come from many different sources, including electromagnetic interference (EMI) ...

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.

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 ...

Many error-correcting codes (ECCs) are proposed in the industry’s literature for correcting bit errors present in the received data. We will discuss Hamming codes that are used to correct singlebit ...

I got into an argument with a colleague about RAID levels (specifically RAID5) and whether the redundancy was accomplished through parity or ECC. The standard sources all refer to the RAID5 array ...
