Interleaver Design for Serially Concatenated Convolutional Codes: Theory and Application [PDF]
IEEE Transactions on Information Theory, 2004 This 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 ...

Estimation of Convolutional Interleaver in a Non-cooperative Context
2020 22nd International Conference on Advanced Communication Technology (ICACT), 2020In this paper, we propose the method for blind estimation of convolutional interleaver parameters in a noncooperative context by analysing repetitive patterns in interleaved sequences. Simulation results verify that proposed method could effectively estimate convolutional interleaver parameters in a noisy environment.

Blind Estimation of Convolutional Interleaver Parameters
2012 8th International Conference on Wireless Communications, Networking and Mobile Computing, 2012Interleaving, an important technique in digital wireless communications systems, is commonly used to improve robustness against burst errors because it provides a form of time diversity. The unitive mathematical model of the convolutional interleaver was presented for the first time and the blind estimation of convolutional interleaving parameters has ...

Interleaver optimization of convolutional turbo code for 802.16 systems
IEEE Communications Letters, 2009Convolutional turbo code (CTC) has been adopted as an optional channel coding scheme for wireless metropolitan area networks (WMAN) and digital video broadcasting (DVB) owing to its powerful error correction capability and flexibility. In spite of the fact that the internal interleaver of CTC mainly affects the characteristics of the code, interleaving

An improved interleaver design technique for parallel concatenated convolutional codes [PDF]
IEEE International Conference on Communications, 2003. ICC '03., 2004 This paper is aimed at the problem of designing optimized interleavers for parallel concatenated convolutional codes (PCCC) that satisfy several requirements simultaneously: 1) designing interleavers tailored to the constituent codes of the PCCC; 2) improving the distance spectra of the resulting turbo codes which dominate their asymptotic performance;

Adaptive interleaver based on rate-compatible punctured convolutional codes
IEEE Transactions on Communications, 2009This letter focuses on the design of an adaptive bit-interleaved coded modulation (BICM) scheme for frequency selective slow fading channels where the transmitter has certain knowledge of the channel response. In particular, we consider the design of the interleaver stage for a specific convolutional code operating with OFDM modulation.
