Abstract- In wireless communication, the channel state changes repeatedly. In this situation, we select the specification of the Viterbi decoder for the worst case channel state. However, if we select the specification of the Viterbi decoder with such a criterion, the decoder operates inefficiently in the good channel state. In this paper, we propose a specification controllable Viterbi decoder without using adaptive T-algorithm. This decoder provides 21 different specifications and can change its specification dynamically depending on the channel state.
