A Low Power Asynchronous Viterbi Decoder
2019 9th International Conference on Emerging Trends in Engineering and Technology - Signal and Information Processing (ICETET-SIP-19), 2019Todays need is for increased content and bandwidth to drive communication systems, error control coding has a great demand. To maintain high reliable data and to improve the Bit Error Rate (BER), error correction technique like the Viterbi algorithm is one of the promising solutions. Though it is useful for error correction it dissipates large power. A

Convolutional Encoding and Viterbi Decoding
2003We introduce the notion of innovations for Viterbidecoding of convolutional codes. First we define a kind of innovationcorresponding to the received data, i.e., the input to a Viterbidecoder. Then the structure of a Scarce-State-Transition (SST)Viterbi decoder is derived in a natural manner.

Truncation length for Viterbi decoding
IEEE Transactions on Communications, 1991A bound is derived and analyzed for the bit error rate (BER) of a Viterbi decoder with survivor truncation. Estimates of the SNR (signal-to-noise ratio) loss on the AWGN (additive white Gaussian noise) channel due to truncation are obtained for convolutional codes. Larger truncation lengths are required than the smallest value that does not effectively

New feedback Viterbi decoder for digital VCRs
IEEE Transactions on Consumer Electronics, 1995A feedback Viterbi decoder that is not affected by rapid fluctuation in the spacing loss has been developed for digital VCRs. The bit error rate was decreased to less than 1/5 of the value found in conventional Viterbi decoders. >

On the Viterbi decoding algorithm
IEEE Transactions on Information Theory, 1969A new interpretation of the Viterbi decoding algorithm based on the state-space approach to dyamical systems is presented. In this interpretation the optimum decoder solves a generalized regulator control problem by dynamic programming techniques.

Memory Management in a Viterbi Decoder
IEEE Transactions on Communications, 1981Management of the memory contents in a Viterbi decoder is a major design problem for both hardware and software realizations. In a naive implementation, every bit in the memory must be changed (read, modified, and rewritten) for each message bit decoded, and, in addition, some double buffering is required.

Security Aspects of Viterbi Decoding
In this note, the authors propose to consider Viterbi trellises whose “nodes” are compromised and have turned rogue. A “network random refresh” style approach might assist in mitigating the deleterious effects of such rogues.openaire +1 more source
