在CDMA系统中 ,导频功率比是一个重要的工程设计参数 ,能否正确的选取导频功率比将直接影响系统性能和链路容量。文中就导频功率比对系统容量及链路平衡的影响进行了探讨和研究 ,给出了在满足链路平衡条件下恰当的导频功率比范围。
In the CDMA system, the pilot power ratio is an important engineering design parameter. Whether the pilot power ratio is correctly chosen will directly affect the system performance and the link capacity. In this paper, the impact of pilot power ratio on system capacity and link balance is discussed and studied, and the proper range of pilot power ratio is given under the condition of meeting the link balance.
