The paper is devoted to the problem of assessing the intensity of the angular power spectrum phenomenon of the received signals as a function of the propagation conditions in environment. To assess the impact of environment on the angular power spectrum, the multi-elliptical propagation model is used. Evaluation of angular power spectrum is shown as a function of the type propagation environment,...
The purpose of this paper is to assess the impact of transmission parameters of propagation environment on the properties of statistical fading. Assessment is shown on the basis of simulation studies that Doppler multi-elliptical channel model (DMCM) is used. Such parameters as level crossing rates (LCR) and average fade durations (AFD) are applied as a measure of intensity fading. In terms of statistical...
In urban environments, a multipath propagation and the Doppler effect are dominant phenomena that negatively affect the quality of service in wireless communications and realization of location methods. This paper presents the localization method of emission source in urban terrain for NLOS conditions based on the Doppler effect. To this aim, authors use the signal Doppler frequency (SDF) method....
Measurement results show that the motion direction of objects has a significant effect on the deformation of the autocorrelation function (ACF) and the power spectrum density (PSD) of the received signals. However, this fact is not included in the analysis of these characteristics previously presented in the literature. In this paper, ACF and PSD are presented as a function of the receiver (Rx) /...
