| Mar 25, 2020 at 4:57 | comment | added | Gerry Myerson | @Mark, I don't know what exactly OP has in mind for $f$, but nothing OP has written leads me to think its output is meant to be of length $m$. Maybe it's some kind of parity check, and its output is a single bit. | |
| Mar 25, 2020 at 4:28 | comment | added | user6976 | The function $f$ is not defined. I guess it is any function of two variables where the input is a pair of binary words of length $m$ and the output is a binary word of length $m$. So the code words have lengths $6m$, the first half of a word is an arbitrary binary word of length $3m$ and the second half depends on $f$ and is for error checking. Then everything depends on $f$. For example if $f$ is a constant function, then the second halfs of the code words are the same and the usefulness of this code is doubtful. In general, using so many bits for error correcting seems excessive. | |
| Mar 25, 2020 at 3:36 | comment | added | user6976 | $x. y, z$ were not bitstrings a little while ago. | |
| Mar 25, 2020 at 3:17 | comment | added | Bill Bradley | This is an interesting question, but the choice of "ternary" seems unfortunate-- there's a already a whole literature on ternary ECCs, where "ternary" means "base-3". Your codes are binary with special structure. | |
| Mar 25, 2020 at 2:37 | comment | added | user2679290 | x, y, z are bitstrings of length m. Concatenation makes sense. | |

replace trianry by ternary
|
| Mar 24, 2020 at 22:42 | comment | added | user6976 | $x,y$ are by definition $m$-tuples of words. So "concatenation" does not make sense. | |
| Mar 24, 2020 at 20:55 | comment | added | Shahrooz | Does $xy$ means the concatenation of $x$ and $y$? Please give an example for such codes and the function $f$ | |
