Improving Capacity of Soft Handoff Performance in Wireless Mobile Communication Using Macro Diversity
The soft handoff is a process on transferring the on going call from one radio resource to another radio resource without any interruption. Rather, mobile unit looks next base station for possible new connection without breaking the old connection. This transfer of call takes place, when the mobile unit moves far away from old base station and approaches toward new base station. At the far away distance from old base station, the signal to noise power at the mobile unit becomes poorer and the service quality degrades. At this far away distance mobile unit may see the another new base station, which may provide the better signal to noise ratio of the same signal via Mobile Switching Center (MSC).
