A very low power consumption Viterbi decoder LSIC has been developed by using a low supply voltage 0.8μm CMOS master slice process technology. By employing the scarce state transition (SST) scheme, this LSIC achieves a drastic reduction in power consumption below 600μW at a supply voltage of IV when the data rate is 1152kbit/s and the bit error rate is less than 10-3. This excellent performance has paved the way to employing the strong forward error correction and low power consumption portable terminals for personal communications, mobile multimedia communications, and digital and audio broadcasting.
