Systematic t-error correcting/all unidirectional error detecting codes with easy encoding/decoding

Codes which can correct t symmetric errors and detect all unidirectional errors have been shown to be useful in fault-tolerant applications. They provide protection against transient, intermittent and permanent faults. Efficient codes have already been developed for this purpose/ However, for most of these codes it is not possible to obtain a simple encoder and decoder. We have developed a systematic t-error correcting/all unidirectional error detecting code, which is comparable in redundancy to the most efficient known systematic codes with the same capability. In addition, our code is easy to encode and decode.
