Coding theorems for turbo code ensembles [PDF]

IEEE Transactions on Information Theory, 2002
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.

CRGAN-based turbo code interleaver for underwater acoustic communications

ICT Express
This paper proposes a channel response generative adversarial network (CRGAN)-based turbo code interleaver that estimates a channel response and interleaver indices at a transmitter by using a sound speed profile (SSP) and the ocean environments without ...

Exit chart analysis of parallel data convolutional codes [PDF]

, 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

Frequency Domain Hybrid-ARQ Chase Combining for Broadband MIMO CDMA Systems [PDF]

, 2009
In this paper, we consider high-speed wireless packet access using code division multiple access (CDMA) and multiple-input multiple-output (MIMO). Current wireless standards, such as high speed packet access (HSPA), have adopted multi-code transmission ...

Interleaver Optimal Turbo Code pada Kanal Flat Fading

Rekayasa, 2009
Turbo Code is one of the channel encoding technique used in wireless cellular networks are approaching  the limit of Shannon's  theory. Interleaver  is used  to determine  the rules of the randomization technique of bits of information in relation to the

Analysis and Design of Tuned Turbo Codes [PDF]

, 2012
It has been widely observed that there exists a fundamental trade-off between the minimum (Hamming) distance properties and the iterative decoding convergence behavior of turbo-like codes.

Shaping EXIT Functions of Turbo Codes [PDF]

, 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.

BIT ERROR OPTIMIZATION OF CODED OFDM SYSTEM OVER RAYLEIGH FADING CHANNEL [PDF]

Journal of Engineering and Sustainable Development, 2019
Low Density Parity-Check (LDPC) codes are one of the hottest topics in coding theory today. This code invented in the early 1960's, and it having an amazing comeback in the last few years.
