directive gain 双语例句
- 1、
In this paper, a three element superdirective endfire array is designed. The array is much smaller than the conventional Chebyshev ( element spacing is λ/ 2) array with the same directive gain.
本文设计了一种高频段3元超方向性端射阵,在达到相同方向性指标的情况下,该阵列的尺寸远小于传统的切比雪夫旁射阵(阵元间距为λ/2)。 - 2、
In this paper, the main valve width and directive gain for uniform linear array of antennas in phased scanning are estimated.
本文对均匀直线阵列天线在相控扫描过程中的主瓣宽度和方向性系数进行了估算。 - 3、
Calculation of the directive function and the gain of concealed conical scanning antenna
隐蔽锥扫天线方向函数和增益的计算 - 4、
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。
