It has been shown that with probability one the peak to mean envelope power ratio (PMEPR) of any random codeword chosen from a symmetric QAM/PSK constellation is logn where n is the number of subcarriers [l]. In this paper, the existence of codes with nonzero rate and PMEPR bounded by a constant is established.

in this research, the interactions of hcn gas with pristine, ga-, n- and gan-doped of boron phosphide nanotube (bpnts) were investigated by using density function theory (dft). the structure, electrical and nqr parameters, quantum descriptors involving energy gap, global hardness, global softness, electrophilicity, electronic chemical potential and electronegativity were calculated. the adsorpt...

This paper proposes a group-based fingerprinting scheme employing a joint coding and embedding strategy to trace multimedia distribution and proactively prevent the leak of multimedia information. Taking advantage of the prior knowledge on the collusion pattern, we construct compact fingerprints that consist of user sub-codeword and group sub-codeword and are embedded in host signal via spread ...

 Categorization Abstract: Trending topic of newspapers is an indicator to understand the situation of a country and also a way to evaluate the particular newspaper. This paper represents a model describing few techniques to select trending topics from Bangla Newspaper. Topics that are discussed more frequently than other in Bangla newspaper will be marked and how a very famous topic loses its ...

A construction is presented to obtain 3-secure fingerprinting codes for copyright protection. Resistance against collusions of up to three buyers is achieved with a codeword length dramatically shorter than the one required by the general Boneh-Shaw construction. Thus the proposed fingerprints require much less embedding capacity. Due to their very clandestine nature, collusions tend to involve...
