This paper concerns a statistical modelling of wideband radio propagation channel in an indoor environment. An approach of describing amplitudes and excess delays of particular multipath components by means of probability density functions (PDF) was developed. Analysed channel impulse response (CIR) realizations were obtained from frequency-domain measurements carried out in a large laboratory hall.
The paper presents analysis of dependence of distance determination error in localization system based on time of arrival (TOA) measurements, on beam width of antenna radiation pattern. Using narrow beam antennas some multipath components with small delays, causing errors of calculation of distance between antennas, can be eliminated and accuracy of the system can be increased. Analysis bases on results...
The paper presents measurements results of the propagation channel for three types of indoor environments. Basing on these results statistical analysis and comparison of obtained data are presented. Short review of channel profile measurement techniques are also presented. The paper includes discussion of indoor channel propagation type influence on positioning systems accuracy. Measurements were...
