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...

From earlier chapters, we recall the performance of digital communication systems to be evaluated by bit error rate (BER). Influenced by the development of modern probability theory and statistical decision theory, communication theory has been developed to evaluate the performance of digital communication systems and to design more effective systems meeting the need from engineering. The first...

Computer-Aided Design and Applications is an international journal on the applications of CAD CAM. It publishes papers in general domain plus emerging fields like bio-CAD, nano-CAD, soft-CAD, garment-CAD, PLM, PDM, data mining, internet, education, genetic algorithms engines. The aimed at all developers users technology to ptovide solutions for various stages design manufacturing. about technol...

overcoming spatial and temporal limitation, information and communication technology is today considered as the axis and key to sustained development and as the most important criterion for development which has reshaped the world and life patterns and it is, in fact, considered both the cause and the effect of development. identifying and proper using of new opportunities for sustained develop...

Software Defined Radio is a radio communications transceiver system in which all the typical components of a communication system such as mixers, modulators/demodulators, detectors, amplifiers are implemented through software rather than hardware. This approach is helpful because there is a scope of developing a system which is compatible with more than one mobile communication standard [1]. Th...

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 ...

This paper presents a technique to estimate the noise due to electromagnetic waves emitted from electrical appliances working nearby the digital communication system and study their impact towards digital communication systems by using the amplitude probability distribution (APD). A unique noise APD pattern is obtained from each measurement of noise due to electromagnetic induction from electri...
