Abstract

The effects of the propagation path loss coefficient (γ) and power control on the forward-link frequency reuse efficiency (K) of a direct sequence code division multiple access (CDMA) cellular system is investigated. A simple analytical model is developed to express the interference received by a user in the home cell from other base stations based on the inverse power-of-distance γ law. Proper factors for optimum power control performance are estimated according to γ. With these factors, K is improved to twice that without power control for γ between 4.5 and 2.5. The degradation in K as γ is increased is significantly less for CDMA than for the traditional FDMA and TDMA cellular systems
