Spatially coupled turbo codes [PDF]

open access: yes2014 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.

Revisiting the calculation of effective free distance of turbo codes [PDF]

open access: yes, 2008
The expression for the minimum Hamming weight of the output of a constituent convolutional encoder, when its input is a weight-2 sequence is revisited. The new expression particularly facilitates the calculation of the effective free distance of recently

Nested turbo codes for the costa problem [PDF]

open access: yes, 2008
Driven by applications in data-hiding, MIMO broadcast channel coding, precoding for interference cancellation, and transmitter cooperation in wireless networks, Costa coding has lately become a very active research area.

Turbo code

open access: yesScholarpedia, 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]

open access: yes, 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.

Capacity-Approaching Non-Binary Turbo Codes: A Hybrid Design Based on EXIT Charts and Union Bounds

open access: yesIEEE Access, 2018
In this paper, we introduce a novel design approach for capacity-approaching non-binary turbo codes. There are two important factors that impact the performance of turbo codes in general: 1) the convergence behavior of iterative decoding in the low ...

On multiple slice turbo codes

open access: yesAnnales Des Télécommunications, 2005
The main problem with the hardware implementation of turbo codes is the lack of parallelism in the MAP-based decoding algorithm. This paper proposes to overcome this problem by using a new family of turbo codes called Multiple Slice Turbo Codes. This family is based on two ideas: the encoding of each dimension with P independent tail-biting codes and a

Reed-Solomon Turbo Product Codes for Optical Communications: From Code Optimization to Decoder Design

open access: yesEURASIP Journal on Wireless Communications and Networking, 2008
Turbo product codes (TPCs) are an attractive solution to improve link budgets and reduce systems costs by relaxing the requirements on expensive optical devices in high capacity optical transport systems.
