Turbo codes and turbo algorithms

open access: greenJournal of Communications Software and Systems, 2017
In the first part of this paper, several basic ideas that prompted the coming of turbo codes are commented on. We then present some personal points of view on the main advances obtained in past years on turbo coding and decoding such as the circular trellis termination of recursive systematic convolutional codes and double-binary turbo codes associated

Efficient Selection of Circular and Random Interleaver for Turbo Codes Multiuser CDMA System with Hadamard Spreading code in AWGN and Rayleigh Fading Channels

open access: greenJournal of Engineering and Sustainable Development, 2012
Recently, turbo codes have attracted many researchers because of the codes astonishing performance at low signal to noise ratio SNR. The interleaver types and lengths is an important part in the design of a turbo code.

Quantum Serial Turbo Codes [PDF]

open access: yesIEEE Transactions on Information Theory, 2008
We present a theory of quantum serial turbo-codes, describe their iterative decoding algorithm, and study their performances numerically on a depolarization channel. Our construction offers several advantages over quantum LDPC codes. First, the Tanner graph used for decoding is free of 4-cycles that deteriorate the performances of iterative decoding ...

Irregular Vector Turbo Codes with low complexity

open access: yesEURASIP Journal on Wireless Communications and Networking, 2022
The term Block Turbo Code typically refers to the iterative decoding of a serially concatenated two-dimensional systematic block code. This paper introduces a Vector Turbo Code that is irregular but with code rates comparable to those of a Block Turbo ...
