Abstract
In this paper, we discuss the procedures how to make Viterbi decoder faster. The implementation in Intel CPU with SSE4 parallel processing instruction sets and some other methods achieves the decoding speed 47.05 Mbps (0.64 Mbps originally). The DVB-T mode used in Taiwan needs 13.27 Mbps to achieve real-time reception, so our implementation of software Viterbi decoder takes only 28% CPU loading.
