Binary-ternary mixed code

Binary-ternary mixed code[1]

Description

Encodes \(K\) states (codewords) in a string of \(n_1+n_2\) coordinates, with the first \(n_1\) coordinates being binary, and the last \(n_2\) coordinates being ternary.

Protection

See Ref. [2,3] for bounds on binary-ternary mixed codes.

Notes

Binary-ternary mixed codes have been used in football pools, in which \(n_1\) of the matches result in either a win, a loss, or a draw, but \(n_2\) of the matches are assumed to have only two of the three possible outcomes [1].
