代码说明:

维特比译码算法被利用卷积码的解码。再一次在两种方法,可以进行解码。一种方法被称为硬判决译码的海明距离度量以用作执行解码操作,而软判决译码采用欧氏距离作为度量。正如在前面的帖子之一软判决译码提高硬判决译码相比很大程度上代码的性能。维特比算法 (VA) 解码涉及三个阶段,即 1) 分支度量计算2) 路径度量计算3) 跟踪操作

    电磁波电场强度的取向和幅值随时间而变化的性质,在光学中称为偏振。如果这种变化具有确定的规律,就称电磁波为极化电磁波(简称极化波)。如果极化电磁波的电场强度始终在垂直于传播方向的(横)平面内取向,其电场矢量的端点沿一闭合轨迹移动,则这一极化电磁波称为平面极化波。电场的矢端轨迹称为极化曲线,并按极化曲线的形状对极化波命名。因此如果E的失端轨迹是圆,则此电磁波称为圆极化波。(The properties of the orientation and amplitude of the electric field intensity of electromagnetic waves vary with time, which are called polarization in optics. If this change has a definite law, the electromagnetic wave is called polarization electromagnetic wave (called polarization wave). If the electric field intensity of the polarized electromagnetic wave always orientations in the plane perpendicular to the propagation direction, the terminal point of its electric field moves along a closed path. Then the polarized electromagnetic wave is called the plane polarized wave. The vector end track of the electric field is called the polarization curve and is named for the polarized wave according to the shape of the polarization curve. Therefore, if the lost track of E is a circle, the electromagnetic wave is called a circular polarization wave.)
