Serial concatenation of a block code and a 2D convolutional code
Multidimensional Systems and Signal Processing, 2018In this paper we study two different concatenation schemes of twodimensional (2D) convolutional codes. We consider Fornasini–Marchesini state space representation of 2D linear systems to describe our concatenated codes. Also we present upper and lower bounds on the distance of the proposed concatenated codes.

Spatially-Coupled Serially Concatenated Codes with Periodic Convolutional Permutors
2021 11th International Symposium on Topics in Coding (ISTC), 2021Spatially-coupled serially concatenated codes (SC-SCCS) are a class of turbo-like codes constructed by interconnecting a sequence of SCCS using a set of block permutors. At short block lengths, however, the bit-error-rate (BER) performance of SC-SCCS constructed by independent block permutors exhibits a high error floor.

An Upper Bound on the Minimum Distance of Serially Concatenated Convolutional Codes
IEEE Transactions on Information Theory, 2004This paper derives an upper bound on the minimum distance of serially concatenated convolutional codes. The resulting expression shows that their minimum distance cannot grow more than approximately K1-1/df (O) , where K is the information word length, and df (O) is the free distance of the outer ...

Design of rate-compatible punctured serial concatenated convolutional codes
2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004A new design criterion to obtain well performing rate-compatible serial concatenated convolutional codes (SCCC) families is proposed. To obtain rate-compatible SCCCs, the puncturing is limited to inner coded bits. However, the puncturing is not restricted to inner parity bits, but extended also to inner systematic bits, thus obtaining high rate SCCCs ...

Performance of Serial Concatenated Convolutional Codes on faded channels
International Conference on Information Society (i-Society 2011), 2011An analysis of performance of Serially Concatenated Convolutional Codes (SCCC) is evaluated on Additive White Gaussian Noise model channel, which is used as a basis, and actions of SCCC on Raleigh flat slow and flat fast faded channels are evaluated in this research work. In DCS the SCCC are utilized to reduce the bit error rates. SCCC encoder consists

Iterative MAP decoding for serial concatenated convolutional codes
IEE Proceedings - Communications, 1998The paper provides detailed computational steps for implementing an iterative serial concatenated convolutional code (SCCC) decoder. These are based on maximum a posteriori probability (MAP) decoding of a single, rate 1/2, recursive, systematic convolutional code, which is reduced to easily implemented equations for forward and backward recursion.

On higher order permutors for serially concatenated convolutional codes
IEEE Transactions on Information Theory, 2006A new parameter set for designing permutors is introduced. It is called the set of higher order separations and can be considered as a generalization of the well-known symbol separation (spreading factor). The respective permutor is called a higher order permutor and we show how such a permutor can be constructed.

2010 IEEE International Conference on Communications, 2010
In this paper, we focus on the design of optimized binary convolutional codes (CCs) and serially concatenated convolutional codes (SCCCs) in the presence of a-priori information (API) at the receiver. First, we propose a design criterion for CCs based on the minimization of the bit error proabability (BEP).

Near-optimum serial concatenation of single-parity codes with convolutional codes [PDF]
IEE Proceedings - Communications, 2005 A class of concatenated codes using convolutional codes and low-density parity check codes as component codes is proposed, extending the author's previous work. A special case is considered serial concatenation of single parity check codes as the outer code, a convolutional code with recursive systematic encoder as the inner code, separated by a random

Interleaver Design for Serially Concatenated Convolutional Codes: Theory and Application
IEEE Transactions on Information Theory, 2004This paper addresses the problem of interleaver design for serially concatenated convolutional codes (SCCCs) tailored to the constituent codes of the SCCC configuration. We present a theoretical framework for interleaver optimization based on a cost function closely tied to the asymptotic bit-error rate (BER) of the block code C/sub s/ resulting from ...
