Are there any forward error correcting code algorithms for a partially reliable channel? [closed]

There are plenty or practical FEC algorithms - RS, Golay, convolutional codes of all sorts. All of them assume that the original data and the FEC code are sent over the same channel with the same ...

Is ECC feature in DDR realized with using Hamming code technique?

The fundamental formula for a Hamming coding is as below: 2^k≥n+k+1 Where k = # of parity bits and n = data bits In a DDR system with ECC feature, every data byte will generate an additional ECC bit ...

Why have apparent memory bitflips in non-ECC memory not increased?

Back in the early 2000s I remember asking about why it was so important that servers use ECC memory. The prevailing wisdom at the time was that systems with lots of RAM would be, statistically, more ...
