Performance Analysis of 3-dimensional Turbo Codes
نویسندگان
چکیده
Turbo codes have gained considerable attention since their introduction by Berrou and al. in 1993 due to their near capacity performance and low decoding complexity. The conventional turbo code is a parallel concatenation of two identical recursive systematic convolutional encoders separated by a pseudo-random interleaver. In this work, we propose a modified three Dimensional Turbo Code (3D-TCs) which combined three parallel component encoders with a large number of state. The proposed 3D-TCs provide strong error correction near the theoretical Shannon limit. We compare also by this work the performance of the proposed 3D-TCs with that of the 2-Dimensional convolutional turbo codes.

An approach to fault detection and correction in design of systems using of Turbo codes
We present an approach to design of fault tolerant computing systems. In this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. Code combining techniques are very effective, which one of these codes are turbo codes. The Algorithm-based fault tolerance techniques that to detect errors rely on the c...
متن کاملAnalysis of 3-Dimensional Turbo Codes
Our paper presents a detailed study of the 3-dimensional turbo code (3D TC). This code which combines both parallel and serial concatenation is derived from the classical TC by concatenating a rate-1 post-encoder at its output. The 3D TC provides very low error rates for a wide range of block lengths and coding rates, at the expense of an increase in complexity and a loss in convergence. This p...

Turbo codes, formed by the parallel concatenation of two recursive systematic convolutional component codes separated by an interleaver, have been proposed for use in a variety of wireless applications, including mobile, satellite and fixed wireless systems. Analysis of their performance requires knowledge of their transfer function, which conveys their distance properties. Using the transfer f...

Turbo coding is a very powerful error correction technique that has made a tremendous impact on channel coding in the last few years. They are recommended for increased capacity at higher transmission rates due to their superior performance over conventional codes. Turbo codes use any one of the decoding algorithms, Maximum a posteriori Probability (log MAP), Soft Output Viterbi Algorithm (SOVA...
متن کاملEXIT Chart Aided Design of Periodically Punctured Turbo Codes
EXtrinsic Information Transfer (EXIT) charts have proved to be an effective tool for studying the convergence behaviour of iterative decoders. However, classical EXIT chart analysis fails to assess the performance of turbo codes in which the systematic bits are punctured periodically. In this letter, a novel 3-Dimensional (3D) EXIT chart technique is proposed for accurately modeling the converg...
