EXIT-Chart-Aided Near-Capacity Quantum Turbo Code Design [PDF]
IEEE Transactions on Vehicular Technology, 2015 High detection complexity is the main impediment in future gigabit-wireless systems. However, a quantum-based detector is capable of simultaneously detecting hundreds of user signals by virtue of its inherent parallel nature. This, in turn, requires near-

Quantum Serial Turbo Codes [PDF]
IEEE Transactions on Information Theory, 2008 We present a theory of quantum serial turbo-codes, describe their iterative decoding algorithm, and study their performances numerically on a depolarization channel. Our construction offers several advantages over quantum LDPC codes. First, the Tanner graph used for decoding is free of 4-cycles that deteriorate the performances of iterative decoding ...

Spatially coupled turbo codes [PDF]
2014 8th International Symposium on Turbo Codes and Iterative Information Processing (ISTC), 2014 In this paper, we introduce the concept of spatially coupled turbo codes (SC-TCs), as the turbo codes counterpart of spatially coupled low-density parity-check codes. We describe spatial coupling for both Berrou et al. and Benedetto et al. parallel and serially concatenated codes.

Irregular Vector Turbo Codes with low complexity
EURASIP Journal on Wireless Communications and Networking, 2022 The term Block Turbo Code typically refers to the iterative decoding of a serially concatenated two-dimensional systematic block code. This paper introduces a Vector Turbo Code that is irregular but with code rates comparable to those of a Block Turbo ...

Where to go from here? New cross layer techniques for LTE Turbo-Code decoding at high code rates [PDF]
Advances in Radio Science, 2018 The wide range of code rates and code block sizes supported by todays wireless communication standards, together with the requirement for a throughput in the order of Gbps, necessitates sophisticated and highly parallel channel decoder architectures ...

Scholarpedia, 2010 Turbo codes are error-correcting codes with performance close to the Shannon theoretical limit [SHA]. These codes have been invented at ENST Bretagne (now TELECOM Bretagne), France, in the beginning of the 90's [BER]. The encoder is formed by the parallel concatenation of two convolutional codes separated by an interleaver or permuter.

Short Low-Rate Non-Binary Turbo Codes [PDF]
, 2012 A serial concatenation of an outer non-binary turbo code with different inner binary codes is introduced and analyzed. The turbo code is based on memory-1 time-variant recursive convolutional codes over high order fields.

Interleaver design for turbo codes [PDF]
2000 IEEE International Symposium on Information Theory (Cat. No.00CH37060), 2001 The performance of a Turbo code with short block length depends critically on the interleaver design. There are two major criteria in the design of an interleaver: the distance spectrum of the code and the correlation between the information input data and the soft output of each decoder corresponding to its parity bits.
