Effects of soft handoff, frequency reuse and non-ideal antenna sectorization on CDMA system capacity
S.-W. Wang, I. Wang · 2002
A digital cellular standard using code division multiple access (CDMA) is currently under development in the United States. Computer simulation results on frequency reuse efficiency and sectorization gain, which are essential in assessing reverse link system capacity, are presented. Nonideal sector antenna pattern, log-linear path loss, and log-normal shadowing are considered. Simulation results on soft/softer handoff statistics, which are important in assessing the tradeoff between network overhead and diversity advantage of soft handoff, are presented. The handoff support requirements for both mobile station and network are assessed.
