Performance of serially concatenated convolutional turbo codes for magnetic recording
IEEE Transactions on Magnetics, 2000 Performance of serially concatenated convolutional turbo codes has been evaluated for the Lorentzian channel using simulation, and experimentally for a real hard disk drive. The experimental results are consistent with simulations, which show a substantial gain over uncoded systems.

An improved design and SOVA algorithm for serial concatenated convolutional code
WCC 2000 - ICCT 2000. 2000 International Conference on Communication Technology Proceedings (Cat. No.00EX420), 2002 Serial concatenated code (SCC) has attracted lots of attention by its excellent performance when employing an iterative decoder. However, the previous research shows that it can obtain good performance only with excessive processing delay. It is analyzed that the decoding structure is the key point of its performance's convergence, as well as the ...

On the input-output weight distribution of serial concatenated convolutional codes
2007 6th International Conference on Information, Communications & Signal Processing, 2007In this paper, first, the calculation method of input- output weight distribution of terminated convolutional codes is shown. Next, it is shown that generalized weight distribution can be obtained since the constraint length is two or three. Furthermore, some analytical results of terminated convolutional codes are shown as function of the number of ...

Serially concatenated codes with euclidean geometry LDPC and convolutional codes
2012 IEEE International Conference on Communication Systems (ICCS), 2012 This paper presents a new scheme of serially concatenated codes. It is formed by a combination of Euclidean Geometry (EG) Low Density Parity Check (LDPC) and Recursive Systematic Convolutional (RSC) codes linked by the row-column interleaver. A modification is proposed on the interleaver, which improves performance of concatenated codes.

Serial concatenation of convolutional code and low rate orthogonal convolutional code [PDF]
Proceedings of IEEE International Symposium on Information Theory, 2002 A novel low rate orthogonal code which is the serial concatenation of convolutional code and orthogonal convolutional code is proposed for high capacity CDMA systems. The BER performance is good and shows no "error floor" phenomenon.

Design of punctured serially concatenated convolutional codes
IEEE Communications Letters, 2005An effective algorithm for the design of punctured serially concatenated convolutional codes (SCCCs) is proposed. The algorithm is based on the density evolution technique, and its main goal is to design a code matching the outer and the inner encoder in order to reduce the bit error rate (BER) in the SNR operating region ranging from the waterfall to ...
