We consider the time of broadcasting in ad hoc radio networks modeled as undirected graphs. In such networks, every node knows only its own label and a linear bound on the number of nodes but is unaware of the topology of the network, or even of its own neighborhood. Our aim is to study to what extent the availability of two important characteristics of a broadcasting algorithm influences optim...

Abstract The real sensitivity of radio astronomical stations is often limited by man-made radio emissions, radio frequency interference (RFI) due to activities such as broadcasting operations, radars, and a variety of communication and radiolocation systems. Time-frequency analysis with high temporal and frequency resolution allows us to detect and excise RFI better than can be done with existi...

DAB (digital audio broadcasting) is a radio system which is depends on EUREKA-147 project. This project was designed by the Members of European Broadcasting Union (EBU). DAB System depends on wireless communication. DAB channel estimation was designed by the OFDM technology that reduces cochannel interference and multipath fading. In this paper we have analyzed bit error rate performance v/s si...

Radio broadcasting technology in this era of compact disc is expected to deliver high quality audio programmes in mobile environment. The Eureka-147 Digital Audio Broadcasting (DAB) system with coded OFDM technology accomplish this demand by making receivers highly robust against effects of multipath fading environment. In this paper, we have analyzed the performance of DAB system conforming to...

________________________________________________________________________________________________________ The prosodic structure of French involves a tight connection between the location of prominent syllables and locations where the flow of speech is divided into prosodic units. Researchers agree that the final (full) syllable of the smallest prosodic unit is prominent. The possibility remains...
