Integer Codes Correcting High-Density Byte Asymmetric Errors

What is it about?

In optical networks without optical amplifiers, the number of received photons never exceeds the number of sent ones. Hence, upon transmission, only asymmetric (1 → 0) errors can occur. Motivated by this fact, in this letter, we present a class of integer codes capable of correcting high-density asymmetric errors within a b-bit byte. Unlike classical codes, these codes use integer and lookup table operations. As a result, they can be implemented “for free,” i.e., without modifying the network hardware.
