Controller_designsimulink
he modeling equation of this system is
MD2X+bDX+kX = F
The transfer function between the displacement X(s) and the input F(s) then becomes
X(s) / F(s) = 1 / (Ms2 + bs +k)

对于一幅输入图像，将产生一幅输出图像，输出图像的每个像素点的灰度值由输入像素点决定，将感兴趣特征的对比度扩展使之占据可显示灰度级的更大部分。使一输入图像转换为在每一灰度级上都有相同的像素点数，均衡化会减少灰度级数。大多数自然图像由于其灰度值分布集中在较窄的范围之内，引起图像细节不够清楚。采用直方图修正后可使图像的灰度间距拉大或使灰度均匀分布，从而增大了反差，使图像细节清楚，达到增强的目的。(For an input image, will produce an output image, the output image gray value of each pixel from the input pixel decided to expand interest in the contrast of features to make it account for more gray levels can be displayed most. Make an input image is converted to grayscale in each pixel have the same points, equalization will reduce the gray series. Most natural images because of their gray value distribution concentrated in a narrow range, causing the image detail is not clear enough. Make the image histogram revised by the gray space widening or so gray uniform distribution, thereby increasing the contrast between the image details clear objective to achieve enhanced.)

test_uncoded_BPSK
说明： 未编码传输AWGN信道测试
每帧的输入是相同的，（不是每帧都不一样，这样可以大幅降低计算量）
在帧比特足够多的情况下，应该可以保证随机性(AWGN channel is not coded transmission test input of each frame is the same, (not every frame is different, this can significantly reduce the computation) are enough bits in the frame of the case, should be able to guarantee randomness)

本文区别于其他传统的人口预测模型，深入分析了当前中国人口的基本情况，以及
最近几年中国人口的发展情况与趋势，针对中国人口基数大、男女比例不协调、乡村人
口城镇化加速、人口老龄化日益严重等显著特点，在各年龄段生育率短期内保持不变的
假设下，建立基本的人口转移回归模型，用于模拟预测短期内中国各类人口数量发展变
化。该模型预测结果显示，中国人口在未来十几年内增长一定幅度后开始下降；与此同
时，人口老龄化、男女比例失调等问题日益严重。该模型短期内的预测效果比较好。
为了使中国将来的人口发展健康、平衡，综合考虑中国以及欧洲一些发达国家和亚
洲一些实行计划生育较早的国家以前以及当前的一些情况，本文提出了修改计划生育政
策的建议。面对日益严重的老龄化现象，我们提出生育率应该参考老龄人口比例这一新
思想，并建立生育率与老龄人口比例的关系模型，用于长期人口的预测。预测结果显示
中国总人口在短期内持续上升，在2025 年到2040 年之间基本保持在14.6 亿的最大值，
然后开始缓慢下降。
两个模型的结果均显示，中国将会面临严重的老龄化和男女比例不协调两个问题。
最后我们提出了适当措施以缓和这两个问题带来的影响。(This is different from other traditional population projection model, in-depth analysis of the current basic situation of China s population, and
In recent years the development of China s population and the trend for China s huge population, gender disharmony, rural people
I accelerated urbanization, the growing aging population and other significant features in the short term fertility of all ages remain unchanged
Assumption, the establishment of basic population transfer regression model, to simulate and predict the short term development of China s various types of population change
Of. The predicted results show that China s population growth in the next decade began to decrease after a certain extent and the same
When an aging population, gender imbalance and other growing problem. The model predicted the short-term results were better.
To make the development of China s future population health, balance, considering China and some developed countries in Europe and A)
