The high and constantly increasing demand to develop radio transceivers with enhanced functionalities, inter-standard portability, higher throughputs, compact physical size, low cost, and longer battery lifetime impose challenges on the radio designer. A Software Defined Radio is capable of meeting these challenges provided (i) enhanced signal processing algorithms with reduced complexities, (i...

The move to digital is a natural progression taking place in all aspects of broadcast media applications from document processing in newspapers to video processing in television distribution. This is no less true for audio broadcasting which has taken a unique development path in the United States. This path has been heavily influenced by a combination of regulatory and migratory requirements s...

Not too surprisingly, a Digital Radio Single Frequency Network (SFN) shares the same properties as a Digital Television SFN. For this reason some of this paper has been taken from [1]. The main differences between radio and TV SFN are due to the different S/N requirements and guard intervals. SFNs do offer significant potential advantages including better coverage, less interference, less power...

In mobile radio communications, various phenomena such as multipath wave propagation, time dispersion, and fading introduce errors like Intersymbol interference (ISI), and other distortions into the signals that are transmitted over wireless channel in mobile radio communications. To combat errors, equalization (a sophisticated set of signal processing techniques), convolution coding and other ...

The Cognitive Radio (CR) technology is a major step forward to address the critical challenge of “spectrum scarcity” in Wireless communications. It is a methodology to develop effective communication systems with the available radio resources and their constraints. This tutorial provides a comprehensive overview on realization of RF Front-End (RF FE) for a Cognitive Radio (CR). It begins with a...

he process of localizing digital games can be significantly different from the process of localizing productivity software; although many of the issues can be discussed in similar terms, the game industry carries with it a series of unique challenges. The term digital game itself requires some clarification. Kerr (2002) defines digital games as “games on a number of different digital platforms ...

A large number of government, semi government and private Radio/TV stations or channels exist in India. All of these stations/channels have got small or big libraries with audio/video collection. The collection comprises of around 22 official languages ranging from Asami to Urdu. The collection also comprises of a variety of recording media ranging from earlier gramophone records to present day...
