LDPC decoder strategies for achieving low error floors

2008 Information Theory and Applications Workshop, 2008
One of the most significant impediments to the use of LDPC codes in many communication and storage systems is the error-rate floor phenomenon associated with their iterative decoders. The error floor has been attributed to certain subgraphs of an LDPC codepsilas Tanner graph induced by so-called trapping sets.

Error floor mechanisms in indoor digital portable communications

[1992 Proceedings] The Third IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2003
By analytical derivation, supported by simulation, the authors develop a closed form theory of the error floor probability of differentially detected MSK in a slowly fading Rayleigh channel with small delay spread. As the major error source they identify the phase jitter generated by group delay bursts coinciding with the frequency deviation of the ...

Iterative Source–Channel Decoding With Reduced Error Floors

IEEE Journal of Selected Topics in Signal Processing, 2011
Audio-visual source encoders for digital mobile communications extract parameters that-due to delay and complexity constraints-exhibit some residual redundancy. This residual redundancy can be exploited by iterative source-channel decoding (ISCD) to improve the robustness against transmission noise by performing soft parameter detection as part of the ...

Error-Reduced Positioning Algorithm on the Uneven Floor

2010 International Conference on Computational Intelligence and Software Engineering, 2010
Conventional 3-dimensional coordinate calculation method required reference nodes at least four. Because of this reason, complexity increased in 3-dimensional coordinate calculation method. In this paper we proposed a new location method in order to solve this kind of problem. The new location method used triangulation method and binary search.

Will the real error floor please stand up?

2012 International Conference on Signal Processing and Communications (SPCOM), 2012
In this paper we continue our study of the influence of message saturation and quantization on the error-rate performance of iterative, message-passing decoders for low-density parity-check (LDPC) codes. We extend our previous analytical results for the min-sum algorithm (MSA) and its variants to the sum-product algorithm (SPA), demonstrating the ...
