Abstract :
This paper gives the theories for the reverse link performance of a cellular DS-CDMA system which supports integrated services, voice and data, with imperfect power control and imperfect sectorization in multiple cells. The system capacity is given by the equations under the effect of power control and sectorization in their imperfections. Numerical results are not discussed. However, the theories which are given are adequate for evaluating the system capacity of integrated services at the same system. The system capacity is expected to decrease with the increasing imperfection of the power control and sectorization. However, although the sectorization is not perfect, dividing the cells into some sectors will help to increase the system capacity
