Abstract :
In this paper, the reverse link capacity is analysed for a multicode direct sequence-code division multiple access (multicode DS/CDMA) system with SIR-based power-control in a multiple-cell environment. Mean and variance statistics of total interference power are derived in order to investigate the effect of two important factors on capacity: (1) the required signal to interference ratio (SIR) and (2) the required number of codes, for each type of user. Unlike most previous works related to SIR-based power control, the effect of multipath fading is explicitly accounted for and mobiles are assumed to connect to the base station whose pilot signal is received with the highest power.
