Performance analysis of handoff algorithm in fiber-optic microcell/picocell radio system

The fiber-optic radio system was proposed to solve the cost problem of micro/picocell system. In this system, all channel elements in a system can be dynamically assigned when the SDS is used. We analyzed the performance of soft handoff used as intergroup handoff in the CDMA based fiber-optic cellular system with a spectrum delivery switch (SDS). Performance is evaluated in view of blocking and handoff refused probability. The numerical results show that the smaller the handoff region or the more the channel, the larger the system capacity. We can also see that the larger queue makes the handoff refused probability lower
