PREMIER Turbo: Probabilistic error-correction using Markov inference in errored reads using the turbo principle

2013 IEEE Global Conference on Signal and Information Processing, 2013
We present a probabilistic algorithm for error correction for high throughput DNA sequencing data. Our approach leverages our prior algorithm PREMIER where sequencer outputs are modeled as independent realizations of a Hidden Markov Model (HMM) and the problem of error correction is posed as one of maximum likelihood sequence detection over this HMM ...

A modified turbo principle for iterative detection and decoding

2008 IEEE International Symposium on Information Theory, 2008
This paper presents a modified turbo principle (MTP) for iterative detection and decoding in multiple-antenna systems whose detector uses the max-log-MAP algorithm. The modified turbo principle intensionally introduces dependency between the messages of the max-log-MAP detector and the decoder.

A novel ARQ technique using the turbo coding principle

IEEE Communications Letters, 1997
A novel automatic repeat request (ARQ) technique based on the turbo coding principle is presented. The technique uses the log-likelihood ratios generated by the decoder during a previous transmission as a priori information when decoding retransmissions. Simulation results show a significant decrease in frame error rate, especially at low-to-moderate E/

Continuous Decoding Based on Turbo Principle for Indoor UWB Channel

2006 10th IEEE Singapore International Conference on Communication Systems, 2006
This paper presents a continuous decoding algorithm combined with adaptive equalization for receiving UWB signal in indoor multipath channel. It provides theoretical analysis and simulation results based on multiuser environment. This new algorithm computes initial forward recursion using training sequence needed by the adaptive equalizer, and uses ...

Turbo-greedy coding for high data rate wireless communications: principles and robustness

IEEE VTS 53rd Vehicular Technology Conference, Spring 2001. Proceedings (Cat. No.01CH37202), 2002
We present a novel iterative-greedy demodulation-decoding algorithm for turbo codes for multiple antenna systems. The decoding algorithm is based on a previously introduced novel greedy detection method for multiuser communications. The iterative-greedy demodulation-decoding algorithm is characterized by the exchange of soft information between the ...

The turbo principle in joint source channel decoding of variable length codes

Proceedings 2001 IEEE Information Theory Workshop (Cat. No.01EX494), 2002
The turbo principle has been widely applied to various detection/decoding problems in recent years. Here we show how the general idea can be extended to a communication scheme where a variable length code is used for data compression followed by a channel code to protect the data against channel errors.

A generalized turbo principle for approximate detection and decoding

2008 IEEE International Symposium on Information Theory, 2008
Optimal joint detection and decoding is infeasible in all but the simplest of communication systems due to the required exhaustive search. A highly popular approximate method for solving this problem is the so-called Turbo principle, in which single-variable beliefs are exchanged between the individual components of the system in an iterative manner ...

Using the turbo principle for exploiting temporal and spectral correlations in speech presence probability estimation

2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013
In this paper we present a speech presence probability (SPP) estimation algorithmwhich exploits both temporal and spectral correlations of speech. To this end, the SPP estimation is formulated as the posterior probability estimation of the states of a two-dimensional (2D) Hidden Markov Model (HMM).

Notice of Violation of IEEE Publication Principles<BR>A novel stopping criterion for turbo decoding

2005 IEEE 61st Vehicular Technology Conference, 2005
This paper proposes a novel stopping criterion for turbo decoding. The new sign variation (SV) criterion calculates the difference of sign values between the extrinsic information of two consecutive iterations. Unlike the methods used so far, it requires no extra data storage.
