Stopping sets in codes from designs

IEEE International Symposium on Information Theory, 2003. Proceedings., 2003
The size of the smallest stopping set in LDPC codes helps in analyzing their performance under iterative decoding, just a minimum distance helps in analyzing the performance under maximum likelihood decoding. We study stopping sets in LDPC codes arising from 2-designs, in particular LDPC codes derived from projective and Euclidean geometries. We derive

Stopping sets and the girth of Tanner graphs

Proceedings IEEE International Symposium on Information Theory,, 2003
Recent work has related the error probability of iterative decoding over erasure channels to the presence of stopping sets in the Tanner graph of the code used. In particular, it was shown that the smallest number of uncorrected erasures is the size of the graph's smallest stopping set. Relating stopping sets and girths, we consider the size /spl sigma/

A Statistical Method for Setting Stops in Stock Trading

Operations Research, 1970
This paper applies the exponential distribution to stock price reactions to determine, at three confidence levels, the critical percentage price reaction beyond which a reaction constitutes a strong likelihood of a major reversal or halt in the stock's present general price trend. We show that these critical values can be used to determine stop losses,

Turbo stopping sets: the uniform interleaver and efficient enumeration

Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005
The performance of turbo decoding on the binary erasure channel (BEC) can be characterized in terms of turbo stopping sets. Apply turbo decoding until the transmitted codeword has been recovered, or until the decoder fails to progress further. Then the set of erased positions that will remain when the decoder stops is equal to the unique maximum size ...

Stopping sets: Gamma-type results and hitting properties

Advances in Applied Probability, 1999
Recently in the paper by Møller and Zuyev (1996), the following Gamma-type result was established. Given n points of a homogeneous Poisson process defining a random figure, its volume is Γ( n ,λ) distributed, where λ is the intensity of the process.
