Finally, proceed from form based on constellation picture of the signal, resume rebuilding the constellation picture to the signal that is received. We change the way of modulation recognition to the shape match of constellation of picture. 最后,从基于信号星座图的形状出发,对接收到的信号进行星座图恢复重建,对星座图的形状进行建模,把调制方式识别转化为形状匹配的问题。
There is a picture/ sound separated ( or combined) filter in the color television modulation and demodulation bay of microwave communication system. 在微波通信系统中的彩色电视调制、解调机架上,有一图像、伴音分路(或合成)滤波器。
The Cathode Factors of the Display/ Picture Tubes with Different Modulation Methods 显示(像)管不同调制方式下的阴极系数
Relation between the cathode factors of display/ picture tubes with different modulation methods is theoretically presented, and it is proven to be true by the experiments with six types of these tubes. 从理论上给出了不同调制方式下显示(像)管的阴极系数的关系,并用六种管型在实验上证明它是正确的。其中外界因素的影响最为重要。
