从经典功率谱估计周期图法原理入手，从理论上分析了其存在的局限性，借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力，进行实验仿真，比较不同的窗函数，不同的数据长度对Welch法谱估计质量的影响，并分析了造成这些影响的原因。(The paper mainly introduces the principles of Periodogram method of classical PSD estimation,analyzes the deficiency of Periodogram method in theory,and makes use of Welch to amend Perodogram method. By the use of simulation in Matlab, the impacts of different window function and different lenghth of data on estimation quality of Welch are discussed and the reasons of the impacts are analyzed.)

这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。 (This is based on space-time block coding MIMO_OFDM communication system simulation design. This system includes the QPSK modem, IFFT modulation, space-time coding and decoding, symbol-based channel estimation training and other communication module.)

说明：  图像反投影重建算法，利用CT采集的数据在进行R_L_滤波后进行反投影得到检测图像。(Image reconstruction algorithm, using the projection of the data collected on CT after R_L_ filter back-projection get detection images.)

在现代化的评价模型中，我们可以用层次分析法建立模型，但是其主观性强，判断矩阵的确定比较困难(In the modern evaluation model, we can use AHP model, but its subjective nature, is difficult to determine the matrix to determine the )
