(2006), pp. 173-182.</i><br /><br />This paper presents an overview of the fields of technology addressed by technical specifications created by the DVB Project (DVB). It serves as an introduction to the section of the special issue of the Proceedings of the IEEE in which a number of very recent DVB technologies will be explained in detail. The overview starts with an explanation of the wide field of application which the members of the DVB Project decided to address over the years. It then discusses the base band processing required for DVB services and looks into the specifications provided for the broadcasting over cable, satellite, and terrestrial transmitters. The concept of broadcasting generic data is explained and the interaction channels supported by DVB will be introduced. Multimedia Home Platform (MHP) facilitates a horizontal market of receivers able to run software programs (applications in DVB terminology)in a well defined way. After a short introduction into the specifications addressing the delivery of broadcast-type content over broad-band IP networks,the concept of broadcasting to handheld devices is introduced. The paper closes with a description of the newest areas of development DVB has decided to tackle.

(1997), pp. 64-75.</i><br /><br />This paper describes the performance of COFDM (coded orthogonal frequency division multiplexing) for digital audio broadcasting (DAB) over various multipath mobile radio channels. COFDM is a channel coding and modulation scheme which mitigates the adverse effects of fading by using wideband multicarrier modulation combined with time interleaving and a convolutional error correcting code. A guard interval is inserted at the transition between successive symbols to absorb the intersymbol interference created by the time domain spread of the mobile radio channel. The decoding process is performed using differential demodulation in conjunction with a soft decision Viterbi decoder. The COFDM evaluation is done by means of computer simulations. A parametric study of the proposed COFDM system is done in this first of a series of papers to determine the optimal system parameter values for operation at a radio frequency of 1.5 GHz. The results show that the parameter values proposed in the standard are indeed well suited for operation at 1.5 GHz. Using the set of optimal parameter values found, the COFDM performance is then evaluated in mobile radio channels typical of different geographical environments. Simulation results confirm the benefit that the system gains from frequency diversity found in the urban and hilly terrain areas Performance evaluation of COFDM for digital audio broadcasting. I.

The use of the Hewlett Packard 11759D Dynamic Ghosting Simulator, which is capable of generating fading models ranging from static transmission conditions to dynamic cases of airplane flutter, tower sway, and reception by a mobile receiver in the simulation is described. All of these conditions can be used to subject future receivers, equalizers, and ghost cancellation circuitries to field-testing within the laboratory environment Simulation of multipath fading/ghosting for analog and digital television transmission in broadcast channels ML Bucher doi:10.1109/11.184729 Broadcasting, IEEE Transactions on, Vol. 38, No. 4.

(1989), pp. 493-503.</i><br /><br />The authors describe a system that combines the orthogonal frequency-division multiplexing technique and a coding strategy associated with diversity in the frequency domain. The system is suitable for digital broadcasting through a particularly hostile urban radio channel. The general principles of COFDM (coded orthogonal frequency-division multiplexing) are explained, and a detailed representation of the signals and the decoding procedure is given. The performance of the system in the selective Rayleigh channel is presented, and the behavior of the system when the conditions of temporal and frequency coherence of the channel are not fully met (very high-speed reception and abnormally extended channel delay spread) is described. The first implementation of a 4-PSK-COFDM systems has been demonstrated at the WARC-ORB 88 conference in Geneva, validating this concept of digital sound broadcasting Digital sound broadcasting to mobile receivers B Le Floch R Halbert-Lassalle D Castelain Consumer Electronics, IEEE Transactions on, Vol. 35, No. 3.
