Design of Rate-Compatible Serially Concatenated Convolutional Codes [PDF]
arXiv, 2006 Recently a powerful class of rate-compatible serially concatenated convolutional codes (SCCCs) have been proposed based on minimizing analytical upper bounds on the error probability in the error floor region. Here this class of codes is further investigated by combining analytical upper bounds with extrinsic information transfer charts analysis ...

Shuffled Decoding of Serial Concatenated Convolutional Codes [PDF]
2021 11th International Symposium on Topics in Coding (ISTC), 2021 Shuffled decoding enables to accelerate the extrinsic information exchange during iterative decoding of concatenated codes. It has already been applied to parallel convolutional codes or low-density parity-check codes. In this article, we propose to apply shuffled decoding to serial concatenation convolutional codes.

On interleaver design for serially concatenated convolutional codes [PDF]
Proceedings. 2001 IEEE International Symposium on Information Theory (IEEE Cat. No.01CH37252), 2002 Serially concatenated convolutional codes are considered. The free distance of this construction is shown to be lower-bounded by the product of the free distances of the outer and inner codes, if the precipices of the interleaver are sufficiently large. It is shown how to construct a convolutional scrambler with a given precipice.

On the design of rate‐compatible serially concatenated convolutional codes [PDF]
European Transactions on Telecommunications, 2007 AbstractA powerful class of rate‐compatible serially concatenated convolutional codes (SCCCs) has been proposed based on minimising analytical upper bounds on the error probability in the error floor region. In this paper, this class of codes is further investigated by combining analytical upper bounds with extrinsic information transfer chart analysis

Design and Performance Analysis of a New Class of Rate Compatible Serial Concatenated Convolutional Codes [PDF]
arXiv, 2005 In this paper, we provide a performance analysis of a new class of serial concatenated convolutional codes (SCCC) where the inner encoder can be punctured beyond the unitary rate. The puncturing of the inner encoder is not limited to inner coded bits, but extended to systematic bits.

Performance Comparison of Serial Concatenated Convolutional Codes and Parallel Concatenated Convolutional Codes on Faded Channels [PDF]
International Journal of Multimedia and Image Processing, 2012 The performance comparison of Serially Concatenated Convolutional Codes (SCCC) and Parallel Concatenated Convolutional Codes (PCCC) is evaluated on Additive White Gaussian Noise model channel, which is used as a basis, and actions of SCCC and PCCC on Raleigh faded channels are evaluated in this research work.

Design of Optimized Convolutional and Serially Concatenated Convolutional Codes in the Presence of A-priori Information [PDF]
IEEE Transactions on Wireless 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. For large signal-to-noise ratios (SNRs), we first propose a CC design criterion based on the minimization of a union bound on the bit error probability ...

Some Extended Results on the Design of Punctured Serially Concatenated Convolutional Codes
Journal of Communications Software and Systems, 2017 The aim of this paper is twofold. On one hand, it presents the results of the search for good punctured systematicrecursive convolutional encoders suitable for application in serially concatenated convolutional codes (SCCCs) operating in two different target regions: at low-to moderate signal-to-noise ratios (SNRs), i.e., in the so called waterfall ...

Rate allocation for serial concatenated convolutional codes
IET Communications, 2007 The paper proposes an analytical method to solve the rate allocation problem in serial concatenated convolutional codes (SCCCs). The goal is to find the best rate allocation between the inner and the outer constituent convolutional codes of an SCCC for constant overall code rate, interleaver size and complexity.
