Digital Audio Broadcasting radio now and for the future


Introduction
The Eureka 147 Digital Audio Broadcasting (DAB)
system is well known to readers of this journal:
there is already a wealth of literature which gives
information on the technical characteristics and the
performance of the system1.
Recently, some debate has started on the role that
DAB could play in the future information highway.

Abstract:

A digital audio broadcasting system that is capable of providing a large number of high quality stereophonic channels to mobile receivers in an environment with severe multipath delay and fading. Optimum combination of frequency and time diversity to guarantee robust performance in the mobile channel, with its multipath delay and frequency-selective fading effects. The system is based upon a dynamic single channel per carrier assignment of each stereo channel to many carriers. Inter symbol interference degradations caused by multipat ....etc

ABSTRACT
Digital radio broadcasting is a technique which gives listeners interference free reception of high quality sound, easy to use radio, and the potential for wider listening choice through many additional station and services. Current analogue FM radio broadcasting systems in VHF band cannot satisfy demands of future ,such as excellent sound quality, large number of stations and small portable receivers and no quality impairment due to multipath propagation. Digital audio technology has set technical qu ....etc

INTRODUCTION

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz to 3GHz for mob ....etc

3D MIMO Scheme for Broadcasting Future Digital TV in Single Frequency Networks
Presented By:
Youssef Nasser, Jean-Fran ois H lard and Matthieu Crussi re
Abstract
This letter introduces a 3D space-time-space block code for future terrestrial digital TV systems. The code is based on a double layer structure designed for inter-cell and intra-cell transmissions in single frequency networks. Without increasing the complexity of the receiver, the proposed code is very efficient to cope with equal and unequal received powers in single f ....etc

Digital Video Broadcasting

Abstract :

DVB, short for Digital Video Broadcasting, is a suite of internationally accepted, open standards for digital television maintained by the DVB project, an industry consortium with more than 270 members, and published by a Joint Technical Committee (JTC) of European Telecommunications Standards Institute (ETSI), European Committee for Electro technical Standardization (CENELEC) and European Broadcasting Union (EBU).
Digital Video Broadcasting (DVB) is a set of standards that define digital broadcasti ....etc
