메모리 오류에 따른 Viterbi Decoder의 정정능력 분석

These days, we use many kinds of memory in various applications, and that applications is used in the earth and in the space. Neutron radiation occurring by Galactic Cosmic Ray and supplying low power can make soft or hard error in memory, and it may give rise to a fatal trouble in the result. In this paper, we have chosen one application (Viterbi decoder) and we have analyzed the Correction Ability of the Viterbi Decoder when arbitrary error occur in memory.
