Exit chart analysis of parallel data convolutional codes [PDF]

open access: yes, 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

Examples of minimal-memory, non-catastrophic quantum convolutional encoders [PDF]

open access: yes, 2011
One of the most important open questions in the theory of quantum convolutional coding is to determine a minimal-memory, non-catastrophic, polynomial-depth convolutional encoder for an arbitrary quantum convolutional code.

Prediction of performance of the DVB-SH system relying on mutual information [PDF]

open access: yes, 2010
DVB-SH (Digital Video Broadcasting-Satellite Handled) is a broadcasting standard dedicated to hybrid broadcasting systems combining a satellite and a terrestrial part. On the satellite part, dedicated interleaving and time slicing mechanisms are proposed

On multiple slice turbo codes

open access: yesAnnales Des Télécommunications, 2005
The main problem with the hardware implementation of turbo codes is the lack of parallelism in the MAP-based decoding algorithm. This paper proposes to overcome this problem by using a new family of turbo codes called Multiple Slice Turbo Codes. This family is based on two ideas: the encoding of each dimension with P independent tail-biting codes and a

Interleaver design for turbo codes [PDF]

open access: yes2000 IEEE International Symposium on Information Theory (Cat. No.00CH37060), 2001
The performance of a Turbo code with short block length depends critically on the interleaver design. There are two major criteria in the design of an interleaver: the distance spectrum of the code and the correlation between the information input data and the soft output of each decoder corresponding to its parity bits.
