directive transmission 双语例句

1. 1、 This kind of tomography inversion with a rectangular block cell, that could process the directive wave and refraction as well as transmission wave, can model and invert the complex velocity structure. It is unnecessary to cognize wave styles and it calcul
   这种层析反演方法以块体为基本单元，可以处理直达波、折射波和透射波，模拟和反演复杂速度结构，不用识别波形，计算速度快。
2. 2、 With the perfect channel state information ( CSI), the MIMO system can reach the optimal performance by realizing directive transmission. Without any CSI, space-time coding is an effective method to improve system performance with transmit diversity gain.
   在发射端已知信道状态信息（CSI）的情况下，利用波束形成技术可以实现最优系统性能；在发射端未知任何CSI的情况下，系统利用空时编码技术实现发射分集来提高传输效率。
