Combined turbo equalization and turbo decoding [PDF]
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 ...

DEEPTURBO: Deep Turbo Decoder [PDF]
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]
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]
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.

Stochastic Decoding of Turbo Codes [PDF]
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.

Block turbo decoding with ORBGRAND
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]
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]
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.

Iterative QR-Based SFSIC Detection and Decoder Algorithm for a Reed–Muller Space-Time Turbo System
An iterative QR-based soft feedback segment interference cancellation (QRSFSIC) detection and decoder algorithm for a Reed–Muller (RM) space-time turbo system is proposed in this paper. It forms the sufficient statistic for the minimum-mean-square error (

Implementation of a Fully-Parallel Turbo Decoder on a General-Purpose Graphics Processing Unit
Turbo codes comprising a parallel concatenation of upper and lower convolutional codes are widely employed in the state-of-the-art wireless communication standards, since they facilitate transmission throughputs that closely approach the channel capacity.
