    MPEG-2 video communications over ATM networks is one of the most active research areas in the field of computer communications. In the transmission process of a variable bit rate video signal over an ATM network, cells are inevitably exposed to delays, errors and losses due to the statistical multiplexing used in these networks. These phenomena affect the quality of the video signal and without ad... View full abstract»

    It is very important having the proper antenna, specially in the MF AM band where achieving the necessary bandwidth in the antenna impedance is a difficult task. This problem is critical in the lower frequencies were the antenna matching to the transmission line generally is very sharp and the best match is obtained only at the carrier frequency with an appreciable power reflection in the lateral ...

    Field strength measurements are made to study the single knife edge diffraction propagation in the hilly terrain of Tirupati, southern India. TV signals originating from Narayana Giri Hill in the VHF band are monitored at 4 different locations of Tirupati for this purpose. The observed values are converted into path loss values and are compared with prediction techniques. An attempt is made to stu... View full abstract»

    Multicast delivery is one of the solutions to reduce the cost in a large video-on-demand (VoD) system. However, multicast transmission makes much more difficult the implementation of interactive functions for individual users and introduces start-up delays for the users, which contradicts the idea of on-demand services. In this paper, we first try to explore and evaluate the performance of differe... View full abstract»

  • Flexible optical fiber CDMA networks using strict optical orthogonal codes for multimedia broadcasting and distribution applications

    Flexible optical fiber code-division multiple-access (CDMA) networks are proposed to support real-time multimedia communication services of constant bit rate (CBR) and variable bit rate (VBR)/multiple bit rate (MBR). Since strict optical orthogonal codes (OOCs) are employed in incoherent optical fiber CDMA networks, their use can strictly guarantee the correlation constraint λ to be the min...

    This paper addresses the implementation of a powerful wide-band mobile channel simulator, which is based on two state-of-the-art 32-bit floating point DSP processors. A key feature of this simulator is the ability to be reconfigured through a common serial interface and virtually simulate a wide variety of different channel models. Additionally, this simulator can be useful to the study of space d... View full abstract»

    This paper describes a novel solution to the problem of bandwidth-efficient digital signal transmission in the presence of dynamic multipath distortion. A burst transmission is comprised of two consecutive data blocks with identical data that have been processed differently. The two data blocks are transmitted adjacent to each other in time so that the time-variable transmission channel will apply... View full abstract»

    The implementation of DTV is forcing every television broadcaster to purchase a new antenna. Choosing the best antenna to meet all of the station's needs is not a simple task. With tower space at a premium, tower leasing rates soaring, and FCC deadlines approaching quickly, the broadcaster faces new and non-traditional issues-for example: Do I co-locate with others? Do I go on the air with a tempo... View full abstract»

    Azimuth pattern analysis of a side-mounted antenna is made keeping reflections separate from the main radiated signal. Each reflection is characterized by a reflection coefficient and path difference in wavelengths at a distant receiving summing point. At each azimuth, the reflections are expressed as echoes accompanying a modulated VSB data pulse. The corresponding receiver equalizer tap weights ... View full abstract»

    OFDM based single frequency networks (SFNs) have been standardized for terrestrial broadcasting systems, for digital audio broadcasting (DAB) as well as for digital video broadcasting (DVB). Due to the multipath tolerance of the OFDM scheme, the receiver is able to combine signals coming from several transmitters, despite of the varying propagation delays, i.e., heavy artificial multipath propagat...
