| Popis: | This paper proposes a new method for computing the delay spread (DS) of the mobile radio channel. The method utilizes a 3D measurement of the received signal at a given position and assumes knowledge of the receiver antenna radiation pattern. The main advantage of this method is that it allows testing of different antennas with only one propagation measurement. It also enables easy DS computation for different orientations of the receiver antenna. The paper describes the new method and investigates its performance by comparing the computed DS values with DS values obtained from measurements directly with the tested antennas. Three typical cellular handset antennas have been used. In addition the variation in DS is shown as function of azimuth rotation of the antenna. |
