The second step of the Viterbi decoding algorithm, the ACS (add-compare-select) unit, is the heart of the process and dictates the performance of the decoder. The ACS operation for each new state in ...

Abstract: This paper describes how Andrew J. Viterbi developed a non-sequential decoding algorithm which proved useful in showing the superiority of convolutional codes over block codes for a given ...

To address this problem, we designed a self-extension Similarity Viterbi algorithm (SimV), which contains three sub-algorithms. Firstly, a basic Viterbi algorithm is employed to find the ...

Figure 3 illustrates the ground and high vegetation points. The watershed algorithm (WA) was employed for individual tree segmentation in the study. WA is an image segmentation algorithm that can ...
