Fully-Parallel Quantum Turbo Decoder [PDF]
IEEE Access, 2016 Quantum turbo codes (QTCs) are known to operate close to the achievable Hashing bound. However, the sequential nature of the conventional quantum turbo decoding algorithm imposes a high decoding latency, which increases linearly with the frame length ...

On the Convergence Speed of Turbo Demodulation with Turbo Decoding [PDF]
IEEE Transactions on Signal Processing, 2012 Iterative processing is widely adopted nowadays in modern wireless receivers for advanced channel codes like turbo and LDPC codes. Extension of this principle with an additional iterative feedback loop to the demapping function has proven to provide ...

Combined turbo equalization and turbo decoding [PDF]
IEEE Communications Letters, 1998 In this paper, the subject of turbo coding in the presence of intersymbol interference channel is investigated. An iterative decoder structure is presented, which combines the channel equalization and the turbo decoding. At each iteration extrinsic information from the channel detector is fed into the turbo decoders, and then their extrinsic ...

Extrinsic Information Modification in the Turbo Decoder by Exploiting Source Redundancies for HEVC Video Transmitted Over a Mobile Channel [PDF]
IEEE Access, 2016 An iterative turbo decoder-based cross layer error recovery scheme for compressed video is presented in this paper. The soft information exchanged between two convolutional decoders is reinforced both by channel coded parity and video compression ...

Stochastic Decoding of Turbo Codes [PDF]
IEEE Transactions on Signal Processing, 2010 Stochastic computation is a technique in which operations on probabilities are performed on random bit streams. Stochastic decoding of forward error-correction (FEC) codes is inspired by this technique. This paper extends the application of the stochastic decoding approach to the families of convolutional codes and turbo codes.

The geometry of turbo-decoding dynamics [PDF]
IEEE Transactions on Information Theory, 2000 Summary: The spectacular performance offered by turbo codes sparked intense interest in them. A considerable amount of research has simplified, formalized, and extended the ideas inherent in the original turbo code construction. Nevertheless, the nature of the relatively simple ad hoc turbo-decoding algorithm has remained something of a mystery.

Extrinsic Information Transfer Charts for Characterizing the Iterative Decoding Convergence of Fully Parallel Turbo Decoders [PDF]
IEEE Access, 2015 Fully parallel turbo decoders (FPTDs) have been shown to offer a more-than-sixfold processing throughput and latency improvement over the conventional logarithmic Bahl-Cocke-Jelinek-Raviv (Log-BCJR) turbo decoders.

Stochastic Analysis of Turbo Decoding
IEEE Transactions on Information Theory, 2005 This paper proposes a stochastic framework for dynamic modeling and analysis of turbo decoding. By modeling the input and output signals of a turbo decoder as random processes, we prove that these signals become ergodic when the block size of the code becomes very large.

Sliding-Window Turbo Equalization and Its Reduced-Complexity Decoding Techniques
IEEE Access, 2022 Turbo equalization is a cooperative error-correcting approach to achieve a target bit-error rate over inter-symbol interference channels. In this paper, we proposed a new turbo equalization, called sliding-window turbo equalization (SW-TE), consisting of
