A flexible processor for FFT and Viterbi algorithms
2012 International Symposium on Communications and Information Technologies (ISCIT), 2012This paper proposes a flexible architecture for the FFT and Viterbi algorithms based on the Common Operator (CO) technique. The FFT and Viterbi structural similarities are investigated to build a common architecture for both algorithms where area is traded against throughput. FPGA implementation and experimental results are discussed in this paper.

A burst-error-correcting Viterbi algorithm
IEEE Transactions on Communications, 1990A dual-mode burst-error-correcting algorithm that combines maximum-likelihood decoding with a burst detection scheme is presented. The decoder nominally operates as a Viterbi decoder and switches to time diversity error recovery whenever an uncorrectable error pattern is identified.

Modified Viterbi algorithm for predictive TCQ
Proceedings DCC'99 Data Compression Conference (Cat. No. PR00096), 1999Summary form only given. A hybrid trellis-tree search algorithm, the H-PTCQ, which has the same storage requirement as PTCQ and, is presented. We assume 2 survivor paths are kept at each state. It is straightforward to extend the algorithm to the cases where n/spl ges/2. Simulation is conducted over 20-second speech samples using DPCM, PTCQ and H-PTCQ.

Iterative Viterbi Algorithm: Implementation Issues
IEEE Transactions on Wireless Communications, 2004We address several issues for implementing the iterative Viterbi decoder. We show that 3-bit branch metric quantization, 7- or 8-bit state metric precision, and a survivor length of five times the constraint length yields little degradation for the iterative Viterbi algorithm (IVA).

Union Bounds on Viterbi Algorithm Performance
AT&T Technical Journal, 1985In the present paper we use transform methods (characteristic function techniques) and contour integrals to derive a closed-form expression for the performance union bound of a general discrete-time system. We show that previously published results may be derived as particular cases of the general formulation developed in this paper.
