The performance and capacity of the mobile system are limited by the multiple access interference (MAI) by other user signal in CDMA system. So, CDMA system divides and services cells to several sector to reduce the interference that is received from other sector. If call traffic load is unequal on each sector, the sector that there are much call traffics can not use the capacity of base station system effectively. In this thesis, We proposed an adaptive sector cell system in order to enhance the performance of the sector system. We studied about the adaptive sector cell system by the method to use whole capacity of base station system effectively and developed of an adaptive sector cell system that presume call traffic load using DSP. In hereafter, is thought to use channel capacity of base station system more efficiently.
