Improving Capacity of soft Handoff Performance in Wireless Mobile Communication using Macro Diversity
Journal Title: International Journal on Computer Science and Engineering - Year 2011, Vol 3, Issue 6
Abstract
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 approach 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 get degrade. 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). Thus the mobile unit may get the same signal from the two different base stations simultaneously. The capacity of the CDMA communication network depends on the diversity technique used. The capacity gain of CDMA communication network can be defined by the comparison of network capacity with macro diversity and without macro diversity. In This paper we represented the capacity as number of users increases with Micro diversity as compared to capacity without Micro diversity.
