the paper presents lower and upper bounds on the number of parity check digits required for a linear code that detects solid bursts of length $b$ or less and simultaneously any $e$ or less random errors. an example of such a code is also provided. further, codes capable of detecting and simultaneously correcting such errors have also been dealt with.

In this paper, two new hybrid algorithms are proposed for decoding Low Density Parity Check (LDPC) codes. Original version of the proposed algorithms named Search Based Weighted Multi Bit Flipping (SWMBF). The main idea of these algorithms is flipping variable multi bits in each iteration, change in which leads to the syndrome vector with least hamming weight. To achieve this, the proposed algo...

This paper considers the optimization of multi-edge type low-density parity-check (METLDPC) codes to maximize the decoding threshold. We propose an algorithm to jointly optimize the node degree distribution and the multi-edge structure of MET-LDPC codes for given values of the maximum number of edge-types and maximum node degrees. This joint optimization is particularly important for MET-LDPC c...

The aim of the future linear colliders is to extend the sensitivity to new physics beyond the reach of the Lhc. Several models predict the existence of new vector resonances in the multi-TeV region. We review the existing limits on the masses of these new resonances from Lep/Slc and Tevatron data and from the atomic parity violation measurements, in some specific models. We study the potential ...

Although the “country runs” of the Asian crisis stopped at the Chinese border, their effects nonetheless included a realignment of real exchange rates and a rise in the risk premium demanded of investments in China. To examine alternative Chinese policy responses, this paper introduces a multi-country, multi-commodity comparative static macroeconomic model. Simulations suggest that, although th...

We introduce an information theoretic measure of statistical structure, called ‘binding information’, for sets of random variables, and compare it with several previously proposed measures including excess entropy, Bialek et al.’s predictive information, and the multi-information. We derive some of the properties of the binding information, particularly in relation to the multi-information, and...

In this paper, we consider the problem of iterative detection and decoding (IDD) for multi-antenna systems using low-density parity-check (LDPC) codes. The proposed IDD system consists of a soft-input soft-output parallel interference (PIC) cancellation scheme with linear minimum mean-square error (MMSE) receive filters and two novel belief propagation (BP) decoding algorithms. The proposed BP ...
