在合成NDVI曲线时，输出某象元NDVI，批处理(a program for NDVI，can be used to batch)

这是用SIMULINK的S-FUNCTION方式编写的系统仿真代码，系统是基于4G网络的核心技术空时分组编码的MIMO-OFDM通信系统的，涉及到空间分集、时间分集和频率分集的有机结合，包括QPSK调制解调、IFFT调制、控制编解码、基于训练符号的信道估计等通信模块。包括main_STBC_MIMO_OFDM和training_symbol两个M文件和一个DOC文件，对各部分的都有详细的代码和注释。(It is used SIMULINK the S-FUNCTION approach to the preparation of the system simulation code, the system is based on the 4G network s core technology space-time block coded MIMO-OFDM communication system, involving spatial diversity, time diversity and frequency diversity of the organic combination, including QPSK modulation and demodulation, IFFT modulation, control of encoding and decoding, symbol-based channel estimation training and other communication module. Including main_STBC_MIMO_OFDM and training_symbol two M file and a DOC file, have detailed the various parts of the code and comments. )

说明：  傅里叶变换能将满足一定条件的某个函数表示成三角函数（正弦和/或余弦函数）或者它们的积分的线性组合。利用傅里叶变换可对语音信号消噪。(ourier transform to meet certain conditions can be expressed as a function of trigonometric functions (sine and/or cosine functions), or their integral linear combination. Fourier transform to denoising the speech signal.)

地形数据显示matlab文件包,这是一个工具程序包.(The terrain data matlab file bag This is a tool package written by foreigners)

在直角坐标中描出不同的坐标，然后连成线，在matlab中显示。(Trace different coordinates in the rectangular coordinates, and then connect line, shown in matlab. )

this is a matlab code for cdma it is a calculation of ber,snr etc.

介绍了某型雷达的目标检测原理, 分析了噪声恒虚警处理中门限系数对目标检测的影响, 提出了一种基于噪声采样的门限系数确定方法, 最后在仿真计算的基础上验证了该方法的可行性。(The constant false alarm rate( CFAR) detection of radar signal plays an important role in radar signal processing. The principle of object detection of a certain radar is introduced, the influence of threshold coeffi􀀁 cient on object detection is analysed, and a method to determin the threshold coefficient based on noise sampling is proposed. Finally, the feasibility of the method is verified through simulation.)

matlab有关信号处理的宝典，书的前面讲的是ｍａｔｌａｂ的用法，怎么样，心动了？(signal processing matlab canon that the front of the book about matlab usage, how heart?)

使用capon进行测向，对加过幅相误差的信号进行测向，得出其俯仰角和方位角的误差(Use capon were finding of increased over amplitude and phase error signal to be measured, draw its pitch angle and azimuth error)
