METHOD OF DETERMINING EFFECT OF RADIO WAVE MULTIPATH FADING |
摘要 |
The invention relates to a method of determining the average effect of radio wave multipath fading in a desired area in a radio system. The desired area of a coverage area of a base station in the system is described by a digital map. The average effect of multipath fading of a transmitter output is determined in different sub-areas of the desired area. In order to reduce the computation amount signal fading parameters are determined at some point of each sub-area by a ray tracing method and the average effect of signal multipath fading in the sub-area is calculated using said parameters. |
