Bounds on the error probability ofml decoding for block and turbo-block codes
Annales Des Télécommunications, 1999Les performances sur canal gaussien de turbo codes en bloc binaires systematiques, avec entrelacement structure ou aleatoire sont estimees, a l’aide de bornes superieures sur les probabilites d’erreurs, pour un decodage a maximum de vraisemblance. Ces bornes relatives a des blocs ou a des bits dependent respectivemet du spectre des distances et de la ...

Design schemes of space-time block codes concatenated with turbo codes
Vehicular Technology Conference. IEEE 55th Vehicular Technology Conference. VTC Spring 2002 (Cat. No.02CH37367), 2003Higher transmission rate and reliable communication over fading channels are major research pursuits of current wireless communications. The space-time block codes (STBC) have been introduced to improve those research goals by simple processing algorithms at the transmitter and the receiver ends.

Trellis Decoding of Linear Block Codes, Turbo Codes
2016During the “long” history of error control coding, especially taking into account that the proof of the Second Shannon theorem is not a “constructive” one, the search for constructive codes to approach the “promised” limits have taken a long period of time.

An alternative approach to the design of interleavers for block “turbo” codes
1996In this paper we describe two methods of interleaving for use with generalized product block codes that can be decoded using a “turbo” decoding strategy. These methods are designed to avoid certain specific error patterns. One method has a number theoretic basis while the other uses finite projective planes. Simulation results are presented.

Concatenation of space-time block codes and "turbo"-TCM
1999 IEEE International Conference on Communications (Cat. No. 99CH36311), 2003For high data rate transmission over wireless fading channels space-time block codes provide the maximal possible diversity advantage for multiple transmit antenna systems with a very simple decoding algorithm. To achieve also a significant coding gain space-time block codes have to be concatenated with an outer code.

Adaptive reliability calculation for block turbo codes
2003 IEEE 58th Vehicular Technology Conference. VTC 2003-Fall (IEEE Cat. No.03CH37484), 2003This work introduces an adaptive method for reliability calculations in iterative decoding. This new method is significant in particular to the class of early termination soft decision decoding algorithms, where instead of relying on approximate calculations to determine the required number of competing codewords, the proposed method determines ...

Source-controlled block turbo coding
2005This thesis proposes the use of block turbo codes for transmitting nonuniform binary memoryless sources over AWGN channels. As opposed to standard convolutional turbo codes, block turbo codes are known to achieve good performance for high code rates, up to 98% of the channel capacity for uniform sources.

Space time block codes with turbo codes
2011This paper aims to provide efficient solutions to improve the power efficiency, like implementation of schemes using MIMO (Multiple-Input Multiple-Output), with error correction codes. Thanks to the union of these two techniques is possible to obtain a low error probability with low power consumption. This paper shows STBC (Space Time Block Codes) with
