Shaping EXIT Functions of Turbo Codes [PDF]

open access: yes, 2008
This paper investigates the shaping of the extrinsic information transfer (EXIT) functions of parallel turbo codes, when the turbo code is used as an outer code in a serially concatenated scheme.

Design of Three-Dimensional Multiple Slice Turbo Codes

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
This paper proposes a new approach to designing low-complexity high-speed turbo codes for very low frame error rate applications. The key idea is to adapt and optimize the technique of multiple turbo codes to obtain the required frame error rate ...

Turbo Equalization Of Nonlinear ISI-channels Using High Rate FEC Codes [PDF]

open access: yesAdvances in Radio Science, 2005
Turbo equalization is a widely known method to cope with low signal to noise ratio (SNR) channels corrupted by linear intersymbol interference (ISI) (Berrou and Galvieux, 1993; Hagenauer et al., 1997).

Multi-non-binary turbo codes [PDF]

open access: yes, 2013
International audienceThis paper presents a new family of turbo codes called multi-non-binary turbo codes (MNBTCs) that generalizes the concept of turbo codes to multi-non-binary (MNB) parallel concatenated convolutional codes (PCCC).

Spatially Coupled Turbo Codes [PDF]

open access: yes, 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.

Exit chart analysis of parallel data convolutional codes [PDF]

open access: yes, 2005
We recently proposed a new class of turbo-like codes called parallel data convolutional codes (PDCCs). The distinct characteristics of PDCCs include parallel data input bits and a self-iterative soft-in/soft-out a posteriori probability(APP) decoder. In

A Proposed Chaotic-Switched Turbo Coding Design and Its Application for Half-Duplex Relay Channel

open access: yesDiscrete Dynamics in Nature and Society, 2015
Both reliability and security are two important subjects in modern digital communications, each with a variety of subdisciplines. In this paper we introduce a new proposed secure turbo coding system which combines chaotic dynamics and turbo coding ...

THE EFFECT OF TRELLIS TERMINATION ON THE PERFORMANCE OF TURBO CODE

open access: yesJournal of Engineering, 2003
This paper introduces a new class of convolutional codes, which is called Turbo Code. Turbo Code was shown to achieve performance in terms of Bit-Error-Rate (BER), which is near Shannon limit.
