Performance of Reverse Link CDMA in a Multi-cell Environment with Moving Cells - Military Communications Conference, 1995. MILCOM '95, Conference Record, IEEE

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 t o undergo flat Rayleigh fading, which is typical of narrowband C D M A 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 b y assuming the power control error to be log-normally distributed. W e present the performance results when the base station of interest moves relative t o other fixed base stations, resulting an overlapping cells, a situation possible in a battlefield environment where the base stations could be mounted on jeeps, tanks, UAVs, etc.
