Precoded PRML, serial concatenation, and iterative (turbo) decoding for digital magnetic recording

L.L. McPheters, S.W. McLaughlin, K.R. Narayanan
1999 IEEE transactions on magnetics  
We show that a high rate serially concatenated code used in conjunction with a precoded partial response equalized magnetic recording channel and iterative decoding can provide similar performance to a  ...  The precoded partial response maximum-likelihood (PRML) read channel is incorporated as the inner code of the concatenated coding scheme and the outer code is a high rate convolutional code.  ...  Consider having just a precoder of the form 1/(1@ D) as the inner code for a serial concatenation system in comparison to having a precoded 1,-D channel as the inner code.  ...

Full rate space-time turbo codes

Youjian Liu, M.P. Fitz, O.Y. Takeshita
2001 IEEE Journal on Selected Areas in Communications  
This paper proposes a class of full space diversity full rate space-time turbo codes. Both parallel concatenated and serially concatenated codes are designed.  ...  We also study the robustness of performance of both turbo codes and trellis codes in space-time correlated fading channels.  ...  More recently, it is proposed in [16] that a space-time trellis code is serially concatenated with interleavers and a rate 1 recursive inner code ( Figure 6 ). QPSK modulation is considered there.  ...

Design of repeat-accumulate codes for iterative detection and decoding

S. ten Brink, G. Kramer
2003 IEEE Transactions on Signal Processing  
Extrinsic information transfer (EXIT) charts are used to design systematic and nonsystematic repeat-accumulate (RA) codes for iterative detection and decoding.  ...  The convergence problems of nonsystematic RA codes are solved by introducing a biregular, or doped, layer of check nodes.  ...  Systematic RA codes are not serially concatenated codes because both the inner and outer decoders receive channel information.  ...
