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).

Turbo Codes Based on Time-Variant Memory-1 Convolutional Codes over Fq [PDF]

open access: yes2011 IEEE International Conference on Communications (ICC), 2011
Two classes of turbo codes over high-order finite fields are introduced. The codes are derived from a particular protograph sub-ensemble of the (dv=2,dc=3) low-density parity-check code ensemble.

Understanding turbo codes: A signal processing study

open access: yesJournal of Information and Intelligence
In this paper, we study turbo codes from the digital signal processing point of view by defining turbo codes over the complex field. It is known that iterative decoding and interleaving between concatenated parallel codes are two key elements that make ...
