Abstract :
With an increase in system bit-rate, unexpected distortion due to the multipath effects may be so serious that the system is rendered inoperative. The reduction of the multipath distortion by beam tilting at a basestation (BS) is theoretically analyzed using multipath propagation models; the system performance, characterized by the critical bit-rate and the probability that multipath distortion can be handled by the system, is evaluated. It is shown that the capability of the system to handle multipath distortion is improved, and the system bit-rate can be selected over a wider range with the introduction of beam tilting than that without beam tilting
