The digital video broadcasting-handheld (DVB-H) service is a new standard for delivering live broadcasting television to handheld terminals and it utilizes UHF bands IV and V (470-862 MHz). However, since the upper limit of the DVB-H frequency band is within a measurable distance of the lower limit of the GSM 900 frequency band, the upper limit will probably be restricted to channel 49 (698 MHz...

The potential applications of high dynamic range analog r-f photonic links include antenna remoting, photonic-coupled phased-array antennas, and cable-television transmission. This paper compares the results obtained with a number of different modulator types and link configurations and gives recent experimental results. Further details on the analysis and results for some of the schemes can be...

h—The problem with popular polarizations in television reception research is that either quantitative or qualitative methodologies considered separately fails to render a complete understanding. Television viewing is both individual and collective. Thus this paper proposes an analytical framework synthesized from alternate approaches not conventionally petitioned in reception research, among th...

Abstract—A printed dipole antenna with back to back asymmetric dual-C-shape uniform strips capable of generating a wide operating band for digital television (DTV) signal reception in the 470–862 MHz band is presented. This antenna is associated with C-shape strips and asymmetric structure, and it operates band in 455–865MHz. By proper adjusting some parameters, it is possible to achieve a broa...

in this paper a new low profile substrate integrated waveguide (siw) probe-fed h-plane horn antenna structure with improved gain is proposed. the proposed antenna consists of two waveguides including a rectangular and a taper one, in which both, first and third modes of the structure are simultaneously excited leading to a uniform field distribution along the radiating aperture of the antenna a...

In a bi-directional Community Antenna Television (CATV) Network the use of a Contention Resolutions Algorithm (CRA) is essential in order to allocate the bandwidth of the multiaccess medium in the upstream direction between the active stations. Two of the CRAs known as exponential backoff algorithm and splitting tree algorithm, have recently been adopted by the Digital Video Broadcasting (DVB)/...
