We present the bit error performance and capacity of the reverse link of a DS-CDMA cellular system, taking into account the effect of power-controlled interfering users from other cells. A convolutionally encoded, BPSK modulated, waveform is considered. The channel is assumed to undergo flat Rayleigh fading, which is typical of narrowband CDMA systems. All the mobile users are power-controlled by their assigned base stations. A cellular CDMA system with 25 cells in a square grid layout is simulated, and the performance in the center cell surrounded by 2-tiers of interfering cells is estimated. The effect of power control is accounted for by assuming the power control error to be log-normally distributed. We present the performance results when the base station of interest moves relative to other fixed base stations, resulting in overlapping cells, a situation possible in a battlefield environment where the base stations could be mounted on jeeps, tanks, UAVs, etc.
