一种对CDMA2000屏蔽的灵巧设计方法

Design method of CDMA2000 shielding device with flexible characteristic

在常规的手机屏蔽策略中,主要还是依靠传统的大功率压制手段进行。这种屏蔽方式功耗大、效能差,越来越难以满足一些系统的需求。而灵巧屏蔽以其省功率、屏蔽效果好等优势逐渐成为了手机屏蔽领域的热点。针对CDMA2000通信体制提出了一种相对简单的屏蔽手段,并着重介绍该平台的设计方法。在此基础之上,利用设计的屏蔽平台进行了相应的测试。测试结果表明,与具有相同功率的白噪声压制相比,该设计具有更加优越的屏蔽性能,可以满足系统的要求。

In the conventional methods of mobile phone shielding,it mainly relies on traditional highpower suppressing method. This method makes high power consumption and poor efficiency,which is difficult to meet system requirements. However, the flexible shielding method with power saving,excellent shielding effect and other advantages has gradually become a hot spot of mobile phone shielding. According to the CDMA2000 communication structure,a relatively simple and flexible method is provided in this paper. The design method of this platform is introduces emphatically. Based on this method,corresponding test was carried out on the shielding platform. The test result indicates that,compared with white noise suppressing of the same power,the platform has the better shielding performance,and can meet the system requirements.
