This paper concerns interference mitigation techniques caused by Long Term Evolution (LTE) mobile system operating in Digital Dividend into Digital Video Broadcasting - Terrestrial (DVB-T) system. Use of filtering as one of the most effective interference mitigation methods has been investigated. Laboratory measurements have been conducted for several commercially available LTE filters in order to...
Frequency reuse factor in LTE network is 1 meaning that the total available bandwidth is used in every cell. Intra-cell interference in the downlink direction is mitigated via orthogonality. Interference is therefore dominated by inter-cell interference, especially at the cell edge. In order to measure the impact of the inter-cell interference, and thus weight the importance and necessity for inter-cell...
A simple non-destructive method for determination of dielectric properties of arbitrary wall in building is presented. The free space method is based on the measurements of reflection coefficients for different angles of incidence. The walls constructed of unknown materials are modeled as homogenous dielectric plate with smooth surface. The measurements are made for the frequency of 2.4 GHz so the...
In this paper we studied some side street effects in a ray tracing street canyon model. Introduction of side streets in a model results with the loss of some rays, and a street canyon model loses it strength. On all simulations 6 rays model is used. On the end, results from the simulations are compared with the ITU-R P.1411-4 recommendation.
Small-scale fading describes rapid fluctuations in signal strength over a small distance. In this paper, small scale fading is modeled with method of finite number waves without dominant one. Statistical test of Central-Limit Theorem is done on that model. Results show the impact of number of waves in model, and how they approximately fulfill terms of Central-Limit Theorem. From distributions of real...
