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 ...

DEEPTURBO: Deep Turbo Decoder [PDF]

2019 IEEE 20th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2019
Present-day communication systems routinely use codes that approach the channel capacity when coupled with a computationally efficient decoder. However, the decoder is typically designed for the Gaussian noise channel and is known to be sub-optimal for non-Gaussian noise distribution.

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 substantial error performance gain.

Analog Slice Turbo Decoding [PDF]

2005 IEEE International Symposium on Circuits and Systems, 2005
This paper presents the design of an analog turbo decoder for DVB-RCS-like applications using a slice architecture. The constituent decoders for different frame lengths are made up of duplicated elements chosen from a small set of reduced-size MAP decoders.

Block turbo decoding with ORBGRAND

2023 57th Annual Conference on Information Sciences and Systems (CISS), 2023
Guessing Random Additive Noise Decoding (GRAND) is a family of universal decoding algorithms suitable for decoding any moderate redundancy code of any length. We establish that, through the use of list decoding, soft-input variants of GRAND can replace the Chase algorithm as the component decoder in the turbo decoding of product codes.

Noncoherent iterative (turbo) decoding [PDF]

IEEE Transactions on Communications, 2000
Previously, noncoherent sequence detection schemes for coded linear and continuous phase modulations have been proposed, which deliver hard decisions by means of a Viterbi algorithm. The current trend in digital transmission systems toward iterative decoding algorithms motivates an extension of these schemes.

Semi-Iterative Analog Turbo Decoding [PDF]

IEEE Transactions on Circuits and Systems I: Regular Papers, 2007
Based on multiple-slice turbo codes, a novel semi-iterative analog turbo decoding algorithm and its corresponding decoder architecture are presented. This work paves the way for integrating flexible analog decoders dealing with frame lengths over thousands of bits.

Understanding turbo codes: A signal processing study

Journal of Information and Intelligence
In this paper, we study turbo codes from the digital signal processing point of view by defining turbo codes over the complex field. It is known that iterative decoding and interleaving between concatenated parallel codes are two key elements that make ...
