| Abstract: | This paper evaluates the performance of interbeam handover in LEO satellite systems. The evaluation is based on an analytical model that is specific for interbeam handover. There are three performance parameters concerned: handover probability, forced termination probability and time availability. From the results it can be seen that the interbeam handover probability depends strongly on the roll-off characteristics of the beam pattern. Forced termination and time availability depend on the quality of the received signal and the selected criterion. A comparison between the use of signal level and position as handover criteria is presented. © 1998 John Wiley & Sons, Ltd. |
