The advance of wireless communications brings in various schemes of wireless digital communication technology. Analog communication and broadcasting services convert into digital services in many countries. The IBOC (InBand On-Channel) system has been developed to work in the same band with the conventional analog radio and broadcasting digital signal simultaneously. HDR (HD-Radio) standard of ...

The rise and development of multimedia and digital information has made communication easier and quicker. However with digital information, comes a responsibility to communicate securely and effectively. As digital information is easy to distribute and alter, therefore it is prone to various attacks and threats. Various security measures are taken while dealing with digital information. Audio S...

In this paper, we focus on a method of analysis of data in a digital communication channel, using the Digital Profiling technique. We believe, in fact, that the massive use of cloud computing and pervasive technology compels us to improve the results of investigative analysis, in case of cyber-crime, reducing the times of job and maximizing the outcome. The method suggested highlights relations...

IEC61850 communication standard for digital substation automation creates a new way to think about conventional protection scheme and configuration of substation. The presence of communication link in process bus makes a revolutionary change for future digital substation. This paper discusses briefly about process bus architecture and presents a new approach of thinking in busbar structure to m...

Computation and digital processes have become integral to everyday communication. The study of how digital media produce meaning, known as computational semiotics, works towards an understanding of the unique properties and characteristics of communications mediated by computers. Articulating and mapping new forms of communication and expression enabled by digital media is important in understa...

The paper outlines the scope of influence of digital factory on the interpersonal communication process and the exemplary description of them. On the basis of a brief description about the theoretical basic concepts of the digital factory occurs the illustration of communicative features in digital factory. Practical coherences of interpersonal communication from a human oriented view were anal...

In this paper, a modified chaotic shift keying method is proposed to transmit digital bits securely over a communication channel. The scheme is based upon encrypting the digital bits 0 and 1 into infinite levels by applying the keystream such that there is no recognisable pattern in the encoded transmitted signal. The encoded transmitting signal generated is shown to resist popular attack metho...

In digital system design, synchronization ensures that operations occur in the logically correct order, and is a critical hctur in ensuring the correct and reliable system operation. As the physical size of a system increases, or as the speed of operation increases, synchronization plays an increasingly dominant role in the system design. Digital communication has developed a number of techniqu...
