Effect of soft handoff parameters and traffic loads on soft handoff ratio in CDMA systems

摘要

In this paper, the relations of soft handoff ratio to soft handoff thresholds setting and the pilot channel power fraction under different traffic loads in CDMA systems are analyzed. Sectorized cells are considered, and the propagation environment includes correlation of shadow fading signals arriving from multiple sectors of the same base station and different base stations. Simulations are made and the results can be referenced for CDMA networks planning and optimizing.
