Abstract :
The error detecting problem for limited magnitude errors over high radix channels is studied. In this error model, the error magnitude does not exceed a certain limit known beforehand. For asymmetric and unidirectional channels, both all and t error detecting codes are studied. Further, close-to-optimal codes are proposed. For symmetric channels, optimal all error detecting codes are given.
