Truncation effects in Viterbi decoding [PDF]
Practical Viterbi decoders often fall significantly short of full maximum likelihood decoding performance because of survivor truncation effects. In the present work the authors study the tradeoff between truncation length and performance loss for the two most common variations of Viterbi's algorithm: best-state decoding (BSD) and fixed-state decoding (

An Efficient Viterbi Decoder [PDF]
Convolutional encoding with Viterbi decoding is a good forward error correction technique suitable for channels affected by noise degradation. Fangled Viterbi decoders are variants of Viterbi decoder (VD) which decodes quicker and takes less memory with no error detection capability.

Adaptive decoding of convolutional codes [PDF]
Convolutional codes, which are frequently used as error correction codes in digital transmission systems, are generally decoded using the Viterbi Decoder. On the one hand the Viterbi Decoder is an optimum maximum likelihood decoder, i.e.

Improved Decoding Algorithms for Convolutional Codes
Introduction. The considered implementation of the Viterbi algorithm provides a reduction in hardware and time costs for decoding convoluted code sequences, and can be used for semi-realistic modeling of existing means of data transmission (for example ...

A reconfigurable Viterbi decoder architecture [PDF]
We present the design and implementation of a novel reconfigurable Viterbi decoder which provides dynamic adaptation to different constraint length and code rate convolutional codes. A decoder that supports constraint lengths from 3-7, and code rates 1/2-1/3 has been synthesized on an FPGA. With a throughput of 20 Mbps, the proposed decoder is suitable
