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 ...

Error Correction Codes (ECC) play an essential role in safeguarding memory systems by detecting and correcting errors that arise from various sources, including ...

The controller has to do two sets of writes or reads — one for the data and one for the code, adding latency to each access. Some controllers can pack multiple codes together for sequential data, ...

The FEC on a CD uses interleaving and layering. A short {32, 28} code is used to correct errors read from the track. Any it cannot correct are marked as erasures and the result is de-interleaved. The ...

The Innsbruck quantum computer calculates with algorithms that switch back and forth between two different quantum error correction codes to realize error-corrected ...

For the uninitiated, low-density parity-check (LDPC) code is an error correction code (ECC) that is used to both detect and correct errors on data that is transmitted ...

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

If you’ve ever sent a text message, played a CD, or stored a file in the cloud, you’ve benefited from error correction. This revolutionary idea dates back to the ...

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method ...
