Optimum non-iterative turbo-decoding [PDF]

Proceedings of 8th International Symposium on Personal, Indoor and Mobile Radio Communications - PIMRC '97, 2002
By observing the structure of the decoder's trellis a new, non-iterative turbo-decoder based on a super-trellis structure is proposed, which exhibits the same decoding complexity as a conventional convolutional decoder possessing an identical number of trellis states.

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.

Hardware Design of Concatenated Zigzag Hadamard Encoder/Decoder System With High Throughput

IEEE Access, 2020
Both turbo Hadamard codes and concatenated zigzag Hadamard codes are ultimate-Shannonlimit-approaching channel codes. The former one requires the use of Bahl-Cocke-Jelinek-Raviv (BCJR) in the iterative decoding process, making the decoder structure more ...

Reduced latency turbo decoding [PDF]

IEEE 6th Workshop on Signal Processing Advances in Wireless Communications, 2005., 2005
Reduced latency versions of iterative decoding of turbo codes are analyzed in this paper. The proposed schemes converge faster than the standard and plain shuffled approaches. EXIT chart is used to analyze the performance of the proposed algorithms. Both theoretical analysis and simulation results show that the new schedules offer better performance ...

Iterative QR-Based SFSIC Detection and Decoder Algorithm for a Reed–Muller Space-Time Turbo System

Entropy, 2017
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 (

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

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.
