Performance of the Viterbi Algorithm on a Polya Channel
نویسنده
چکیده
The Performance of the Viterbi algorithm with a new Polya contagion noise process is analyzed. The markov channel is the memory channel usually studied in the bibliography. The Polya channel was introduced years ago as a special case of a memory channel. In this work, the Polya contagion scheme is considered as a noise process and a GaussPolya noise model is introduced this way in order to perform soft decision decoding. The behavior of the Viterbi algorithm on a given recursive sequential circuit is analyzed under this special case of memory channel. Keywords— Viterbi, Polya, contagion, maximum likelihood.

متن کاملMulti-channel MLSE equalizer for GSM using a parametric channel model
In this paper, we propose a novel algorithm for the MLSE equalizer for the GSM system. Speci cally, we use a parametric model for the channel, to obtain a modi ed Viterbi Equalizer which we refer to as the Parametric Channel-Viterbi Equalizer (PC-VE). In contrast to the conventional Viterbi Equalizer with a FIR channel description, the PC-VE avoids the linear approximation error and has a lower...
