Abstract :
In this paper, we evaluate both the path loss as well as stepping of power control impact on the CDMA capacity. First, different path loss exponents varying from 2 to 4 are used for the simulation and corresponding interference ratios are calculated for all cells involved in the simulation to study the impact of path loss exponents on capacity. Second, different power stepping sizes are applied to the simulators. Again, the corresponding interference ratios and the interference (rise over NoW) are calculated to study the impact on the CDMA system because of the power control stepping. A power control stepping effect model is developed and compared with simulation with power control on flat terrain with flat fading and uniformly distributed mobiles. The capacity is analyzed based on a set of predefined values of forward and reverse links system parameters
