Parallel, concatenated, convolutional turbo codes promised an exciting breakthrough in error-correction-coding technology but still had problems (see sidebar “ ECC goes turbo “). The first problem was ...

Accurate analysis of (non-punctured) convolutional codes using the state diagram and transfer function has been well-established; but for punctured convolutional codes, approximation has been the ...

In this paper, we propose the use of a Hidden Markov Model (HMM) for the reconstruction of convolutional codes and decoding by the Viterbi algorithm. Furthermore, to implement soft-decision decoding, ...

You can implement FEC techniques for linear block codes (Reed-Solomon codecs) and convolutional codes (Viterbi codecs). To understand this general implementation, look at the hardware behind these ...
