系统容量 ：在保证通信质量的前提下，功率控制算法能够支持的用户数量和数据传输速率。
码片同步 ：指接收端的扩频码与发送端的扩频码在码片时序上的同步。这一过程需要解决码片时序的捕获和跟踪问题，通常采用滑动相关法、匹配滤波法等技术实现。
It organizes know-how and business processes into levels defined by actions happening, and it outlines how an company can create an interface to speak between these levels.
数字信号相乘，由于伪随机码速率快，扩展了传输带宽（伪随机码带宽远大于信号带宽，扩展信号频谱），在接收端，用相同的伪随机码序列

Network Infrastructure: The cellular network infrastructure contains base stations, mobile switching facilities, and data facilities that take care of and route EVDO traffic. Base stations connect with mobile devices, while mobile switching centers take care of call routing and take care of network sources.
是利用电磁波的反射特性来探测目标。雷达发射机产生特定频率、波形的电磁波，经由天线向空间定向辐射，形成具有一定方向性的波束。当波束遇到目标物体时，电磁波会在目标表面发生反射，其中部分反射波沿着原路返回被雷达天线接收，接收机对微弱的回波信号进行放大、滤波、解调等一系列精细处理，提取出目标的距离、方位、速度等关键信息。这一过程如同向黑暗中投掷石子，通过聆听回声来判断周围物体的位置
