【摘要】 文中通过蒙特卡洛仿真,研究了CDMA20001x和CDMA20001xEV-DO系统在不同频率配置、不同组网方式下共存的系统容量损失情况。仿真结果表明,共存系统容量随着两个系统的频率间隔的增加而减小,随着组网方式的改变而改变,相同条件下1:1的共站组网方式时系统容量的损失最小。此外,根据仿真分析的结果,给出了减少系统间干扰的措施。更多还原

【Abstract】 This paper, by the Monte-Carlo simulation method, principally analyzes the network performance due to the co-existence of CDMA2000 1x and CDMA2000 1xEV-DO under the different frequencies disposions and sites distributions. The simulation result shows that the capacity loss of the co-existent systems increases while the space of the frequencies decreases. Also the capacity loss changes while the site distribution changes. The capacity loss is minimum when the site distribution is 1:1. Finally several methods for reducing the interference impact on the performance are given.更多还原
