    A propagation model is presented for characterizing the channel response for digital systems in urban areas where multiple reflections from buildings are encountered. A deterministic ray-tracing propagation model is used to predict the time delay and fading characteristics for the channel in a hypothetical urban area. The analysis shows that due to multiple reflection and diffraction sources, the ... View full abstract»

    The paper addresses the use of the radio data system (RDS) for datacasting road traffic information. It is concluded that, although RDS may be essential to the early phases of introduction of novel advanced traffic information systems (ATISs), FM subcarrier transmission does not offer a spectrum-efficient solution for large-scale ATIS datacasting. The conclusions are believed relevant to the spect... View full abstract»

    It was found previously (Ward and Zhang 1992) that the two-dimensional Fourier transform of a picture impaired by intermodulation beat products contains distinguishable pulses. Each product results in four pulses with special characteristics. The authors further analyze and study the intrinsic properties of these pulses. Based on these properties a method is designed which can detect these pulses,... View full abstract»

    Several aspects of terrain databases (TDBs) used in radio communication system planning tools are considered. It has been found that parameters like grid size, interpolation methods, propagation models, etc. used in this type of application differ from one application to another. Some of these parameters are analyzed in order to evaluate their influence on the overall prediction error View full abstract»

    Theoretical and experimental evaluation of the objective signal-to-noise performance of component video signals is described. Using a mathematical model, an expression for the component video-signal-to-noise ratio, called the display-signal-to-noise-ratio (DSNR), is derived for Gaussian white noise input. Using this model the signal-to-noise performance of 100% saturated primary and secondary colo... View full abstract»
