Abstract:With a Viterbi decoder, the bit error probability of a communication system can be reduced. However, the power consumption of exploiting Viterbi decoder is an overhead to systems. In the Viterbi decoder, the survivor memory unit (SMU) is the most power critical due to data exchanging. A low-power radix-4 Viterbi decoder based on a differential cascode voltage switch with pass gate (DCVSPG) pulsed latch with sharing technique is proposed to process two bits concurrently. The dynamic power of SMU is reduced by t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
