Abstract :
Handover control of indoor pico-cellular radio systems becomes unstable due to severe multipath fading in buildings. The previously proposed decision-avoided handover algorithm can greatly improve the robustness of indoor handover control. This paper analyzes soft handover control algorithms for indoor DS-CDMA systems. The soft handover algorithm exhibits the same robustness as the decision-avoided algorithm. Also, the proposed algorithm can increase the utility of pico-cell base stations, because this approach does not use any channels of the base station receiving handoff
