| Abstract: | This paper,by using the concept of residual capacity,proposes an optimized soft handoff algorithm for multi-traffic CDMA systems.Attenuation of dissemination and load balance are both considered in order to achieve the goal of load balance between cells.The simulation results indicate that,compared to traditional soft handoff algorithm,the novel algorithm reduces the handoff termination probability and raises the system performance. |
