摘要
CDMA网络的覆盖、容量和质量不是相互孤立而是互相制约的,从而导致了网络覆盖规划的复杂性。针对CDMA网络覆盖的复杂特点,对网络规划中的覆盖分析做了详细的研究,在仿真关键参数导频强度设置上提出了一些新的方法,最后在U-NET仿真系统中对提出的方法进行分析比较,实验证明当网络负荷增加到设计负荷时,仍然不用对网络进行大量的调整,网络也不会出现覆盖空洞,用户依然能够比较正常地进行通话,保证网络质量。
Since the coverage,capacity and quality of CDMA network are mutually constrained,but not mutually isolated,the coverage planning of networks is complex.According to the complex characteristics of CDMA network,the coverage ana-lysis in network planning is researched.Some new methods of key simulation parameter setup are proposed.The proposed methods are analyzed and compared in U-Net simulation system.Experiment results prove that when network load is up to the design capacity,it is still unnecessary to adjust network and users still can perform their communication.
