摘要
分析了CDMA2000导频PN序列结构,说明了导频工作原理、导频污染原因以及具体解决方案,最后以兰州联通CDMA网络优化案例为例,对优化前后的主要指标作了说明,并就优化前后Ec/Io统计图作了详细的对比分析.
The frequency pilot PN sequence structure of CDMA2000 was analyzed, and the working principle of frequency pilot, reason of pilot pollution and its solution was explained in detail. Finally, a case of optimization of CDMA network of Lanzhou Unicorn was taken as an example to explain the major parameters before and after the optimization, and the statistical Ec/Io diagrams were also compared in detail.
