Short Low-Rate Non-Binary Turbo Codes
, 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.

Design of Three-Dimensional Multiple Slice Turbo Codes
EURASIP 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 ...

A MODIFIED UNEQUAL POWER ALLOCATION (UPA) SCHEME FOR PERFORMANCE ENHANCEMENT IN BIT REPETITION TURBO CODES IN HIGH SPEED DOWNLINK PACKET ACCESS (HSDPA) SYSTEM [PDF]
Journal of Engineering Science and Technology, 2015 In this paper, a modified optimal power allocation scheme for different bits in turbo encoder has been proposed to improve the performance of Turbo Codes system in High Speed Downlink Packet Access (HSDPA) service. In a typical turbo code in HSDPA system,

Coding theorems for turbo code ensembles [PDF]
IEEE Transactions on Information Theory, 2002 Summary: This paper is devoted to a Shannon-theoretic study of turbo codes. We prove that ensembles of parallel and serial turbo codes are good in the following sense. For a turbo code ensemble defined by a fixed set of component codes (subject only to mild necessary restrictions), there exists a positive number \(\gamma_0\) such that for any binary ...

Simple Metrics for Turbo Code Interleavers
Electrica, 2019 In this paper, we consider the searching for good turbo code interleavers. Especially, we focus on the permutation polynomial interleavers. Three key properties (i.e.

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

Advanced Materials, EarlyView.Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.
