This paper describes an efficient implementation of the Viterbi decoding algorithm on the ZSP500 digital signal processor (DSP) core. It starts with an introduction to convolutional coding and Viterbi decoding as a method of forward error correction in communication systems. An introduction to the ZSP500 architecture is followed by a description of special instructions for performing the Trelli...

The strategy of dynamic programming reduces the complexity of a search problem which decomposes into frequently-reused instances of the same problem. You encountered dynamic programming for n-gram segmentation in HW4. We have also discussed two more dynamic programming algorithms in lecture: Viterbi and forward-backward. For HW5, you will need to implement the Viterbi algorithm. The forward-bac...

Instead of using the line...

By using viterbi decoder the power can be reduced according to number of stages used in each block. The efficient way to reduce data corruption in digital communication channels using various decoding algorithm. Although hardware implementations of decoding algorithms, (i.e.,) Viterbi algorithm, have shown good noise tolerance for error-correcting codes, these hardware implementations require a...

We describe a natural alternative for training sequence labeling models, based on MIRA (Margin Infused Relaxed Algorithm). In addition, we describe a novel method for performing Viterbi-like decoding. We test MIRA and contrast it with other training algorithms and contrast our decoding algorithm with the vanilla Viterbi algorithm.

A taxonomy of VLSI grid model layouts is presented for the implementation of certain types of digital communication receivers based on the Viterbi algorithm. We deal principally with networks of many simple processors connected to perform the Viterbi algorithm in a highly parallel way. Two interconnection patterns of interest are he “shuffleexchange” and the “cube-connected cycles.” The results...

Convolutional code is relatively popular technique in decreasing the bit error rate (BER). The transmitted data under Additive white Gaussian noise (AWGN) channel can be successfully recovered at the receiver side by using Viterbi algorithm based on hidden Markov model (HMM) to decode and correct the data. Viterbi algorithm work by calculating the hamming distance, comparing the path metric, an...
