This article explores the empirical validity of the generalization that scrambling of indefinites correlates with the loss of non-specific readings. There are two issues relevant to the generalization that have not been fully investigated in previous literature. The first is the status of contrastive readings, which do survive scrambling. If contrastive readings are non-specific, and it is argu...

The WCDMA downlink is limited by Node-B cell power and the number of channelization codes. With upcoming capacity enhancement techniques, like MIMO and HSDPA, the potential limitation in channelization codes becomes visible more frequently. The WCDMA standard allows for allocation of traffic on a secondary scrambling code, which is non-orthogonal to the primary scrambling code. This paper analy...

195pt and 1h nmr has been used to show that addition of chlorine and bromine to [pt(cn)4]2_ in presence of perchloric acid in water results in cyanide and water scrambling with formation of eleven complexes of the type [pt(cn)4-ncl(h2o)n+1](n-1)+ (n=0, 1, 2, 3, 4). addition of nbu4oh to this solution gives (nbu4)2[pt(cn)4cl(oh)]. nmr measurements in acetone also show cyanide and hydroxyl group ...

The Soból sequence is the most popular quasirandom sequence because of its simplicity and efficiency in implementation. We summarize aspects of the scrambling technique applied to Soból sequences and propose a new simpler modified scrambling algorithm, called the multi-digit scrambling scheme. Most proposed scrambling methods randomize a single digit at each iteration. In contrast, our multi-di...

This Report describes the development of a scrambling system for overnight downloading of television programmes to video cassette recorders – the BBC Select service. The scrambling techniques used successfully for many years for satellite broadcasting and cable distribution are often unsuitable for UHF terrestrial broadcasting using VSB-AM. This is because of the constraints of equipment, such ...

Criterion for choosing chaos map to drive image bit permutation based on chaos permutation information entropy is proposed. An algorithm for image bit permutation is designed based on the fact that the output trajectory of chaotic system is very unpredictable. Image smallest granularity scrambling, namely, bit space maximum scrambling is implemented by applying the chaos that has been selected....

The initial search procedure in WCDMA is used to identify the scrambling code used by the base station that has the lowest path loss coefficient of the received signal among all the other base stations. The timing relationship between base stations is asynchronous in WCDMA system. So the three-step cell search algorithm is introduced in 3GPP protocols in order to fast identify the special base ...

In this paper, a novel scheme for video scrambling is introduced for Distributed Video Coding. The goal is to conceal video information in several applications such as video surveillance and anonymous video communications to preserve privacy. This is achieved by performing a transform domain scrambling on both Key and Wyner-Ziv frames. More specifically, the sign of the scrambled transform coef...

Based on the security of information transmission through network in the information society, the paper puts forward covert communication technology which is more reliable than the prior encryption algorithm, analyzes channel covertness and information hiding of covert communication technology based on spread-spectrum communication technology, and establishes a covert communication system inclu...
