Zigzag codes and concatenated zigzag codes

1999 Information Theory and Networking Workshop (Cat. No.99EX371), 2003
This paper introduces a family of error-correcting codes called zigzag codes. A zigzag code is described by a highly structured zigzag graph. Due to the structural properties of the graph, very low-complexity soft-in, soft-out decoding rules can be implemented.

Partially concatenated convolutional codes

Proceedings. 2001 IEEE International Symposium on Information Theory (IEEE Cat. No.01CH37252), 2002
We present a new code construction called partially concatenated convolutional codes. Parallel concatenated convolutional codes (turbo codes) and serially concatenated convolutional codes can be regarded as special cases of this construction. However, proper partitioning of the outer code sequences provides a new degree of freedom for code design.

Cyclic concatenated codes with constacyclic outer codes

IEEE Transactions on Information Theory, 1992
Summary: The known construction of cyclic concatenated codes is based on the fact that the inner code is a cyclic minimal code, the outer code is cyclic, and the lengths of the inner and outer codes are relatively prime. Here, it is shown that if the outer code is a suitably chosen constacyclic code the overall concatenated code is always cyclic ...

Concatenated Coding Systems and Turbo Codes

1999
As discussed in Chapter 1, one of the goals of coding research is to find a class of codes and associated decoders such that the probability of error could be made to decrease exponentially at all rates less than channel capacity while the decoding complexity increased only algebraically.

On BEP of a generalised concatenated coding

1999 Information Theory and Networking Workshop (Cat. No.99EX371), 2003
This paper is mainly concerned with the combination and decomposition of linear block error-control codes for satellite and deep space communications. These problems are posed because concatenated codes are not optimum codes in most cases. Even when the inner and outer codes are optimum codes individually, their combination is still not optimum.
