Low-density parity-check (LDPC) codes have attracted much attention over the past two
decades since they can asymptotically approach the Shannon capacity in a variety of data …

Reliable data transfer aims to guarantee that the destination node can successfully receive
what have been sent to it, and the basic mechanisms extensively for this purpose in radio …

In large-scale distributed computing clusters, such as Amazon EC2, there are several types
of “system noise” that can result in major degradation of performance: system failures …

Information theory and inference, often taught separately, are here united in one entertaining
textbook. These topics lie at the heart of many exciting areas of contemporary science and …

Since online exams still presents security problems, the certification exams are frequently
taken by paper-based exams. This work presents the results of a survey and interviews …

We design low-density parity-check (LDPC) codes that perform at rates extremely close to
the Shannon capacity. The codes are built from highly irregular bipartite graphs with …

We consider the following natural model: customers arrive as a Poisson stream of rate/spl
lambda/n,/spl lambda/< 1, at a collection of n servers. Each customer chooses some …

Binary low density parity check (LDPC) codes have been shown to have near Shannon limit
performance when decoded using a probabilistic decoding algorithm. The analogous codes …

We propose a general method for constructing Tanner graphs having a large girth by
establishing edges or connections between symbol and check nodes in an edge-by-edge …

Convolutional low-density parity-check (LDPC) ensembles, introduced by Felström and
Zigangirov, have excellent thresholds and these thresholds are rapidly increasing functions …
