“…UTD (uniform theory of diffraction) based propagation model including only single edge diffraction was reported indeed [8]. The main contribution of this paper with respect to the last reported one in [5] is the improved modeling procedure with higher emphasis on the time delay of each ray contribution with respect to the minimum delay (direct) path. Thus the main features of the developed wideband model are:…”

“…The effects of scatterers in discrete delay ranges are lumped together into individual "tap" with the same delay. Each tap represents a single ray contribution to the received signal and has gain, which varies in time according to the standard narrowband channel statistics [5]. The taps are usually assumed to be uncorrelated from each other.…”

“…Usually the PDP is discretized in the delay dimension to yield n individual taps of power P 1 , P 2 ,,P n . Each tap-gain process may be Rice or Rayleigh distributed [5]. The PDP can be characterized by various parameters:…”

“…In general these models can be classified in to narrowband and wideband models. The first one is concerned with voice/data applications of smaller signal bandwidth with respect to the coherent band-width of the channel [5,6]. Lower attention has been given for wideband modeling of LMS channel, which becomes critically required for multimedia applications of higher bit rate.…”

This paper presents a propagation model for land-mobile-satellite (LMS) wideband radio channel in built-up environment. The model characterizes the behavior of the radio channel, under shadowing and multipath effects due to buildings, with variation of the elevation angle of the satellite. The wideband parameters (coherent bandwidth and time delay spreading) for LMS channel, in residential and urban environments, are computed. These parameters can be considered as a measure of the amount of ISI (inter-symbol interference) of the radio channel, which distorts the received signal and accordingly increases the bit error rate. The calculated values for these parameters using our model, show very good agreement with the corresponding measured ones, which accordingly shows the validity of the developed model for radio channel design in satellite mobile communication systems

This paper presents the method to analyse the effect of building on the L-band Mobile Satellite (MS) system using low-power Global Positioning System (GPS) receiver. The method includes measurement, experimental and data analysis. The analysis of the signal performance under building effect measurement was carried out with respect to the signal to noise ratio (SNR), elevation and azimuth angle. In measurement method, the National Marine Electronics Association (NMEA) sentences obtained from the satellite via GPS receiver was used to get the signal propagation parameters. The NMEA Extractor used to extract the NMEA data using C++ programming language and Ngraph software to construct the graphical presentation for analysis method. The analysis shows relationship between SNR and elevation and azimuth angle. The comparison between open space and building effect was carried out and the results have shown that the presence of the building affect the quality of the satellite signal received.
