OFDM发送端程序集合，比较详细的各个部分，希望对大家有帮助(OFDM transmitter collection procedures, the various parts of a more detailed, in the hope that we have to help)

制作运用Broyden迭代法解线性方程组的用户界面(Making Broyden iteration method by solving linear equations of the user interface )

gold序列的生成 PN序列Gold序列极好的自相关性 生成64位的PN序列 (Gold sequence generated PN sequence gold sequence excellent correlation )

用于计算拟合曲线的上下包络，需要用matlab来实现(Used to calculate the fitting curve of the upper and lower envelopes, using matlab to achieve)

MIMO FMCW Approach for detection and tracking of the targets

DTMF(双音多频)是用两个特定的单音频组合信号来代表数字信号的一种编码技术。两个单音的频率不同，代表的数字或实现的功能也不同。可采用8种频率代表电话机上的16个按键，10个数字键0~9和6个功能键*、#、A、B、C、D。具体的频率组合见参考书。要求： (1) 根据键盘输入的符号，利用MATLAB产生对应的DTMF信号；(2) 分别利用FFT算法和Goertzel算法计算该DTMF信号的频谱并画出频谱图；(3) 根据频谱图确定DTMF信号所代表的符号是否和输入的符号一致。 (DTMF (Dual Tone Multi-Frequency) is a single with two specific combination of audio signals to represent a kind of digital signal coding techniques. Two monosyllabic different frequency, on behalf of the numbers, or the realization of the functions are also different. Eight kinds of frequency of use on behalf of telephone on the 16 keys, 10 numeric keys 0 ~ 9 and 6 function keys*,#, A, B, C, D. The frequency of specific composition of reference books. Requirements: (1) According to the keyboard input of symbols, the use of MATLAB have a corresponding DTMF signal (2), respectively, using FFT algorithm and the Goertzel algorithm DTMF signal spectrum and frequency spectrum draw (3) According to DTMF signal frequency spectrum to determine represented by symbols and input symbols unanimously.)

基非下采样的Contourlet变换的图像融合，要放到NSCT工具包中执行(Under the base of non-sampling Contourlet transform image fusion, to put the implementation of the toolkit NSCT)

做数据处理，比如做智能诊断样本创建的时候， 如果采集信息有限，但数据量又很大， 可以选择将原始信号就行降采样，来获得更多更可靠的样本(Good collection of information is limited, but the amount of data is so big occasion)

说明：  数据预测之BP神经网络具体应用以及matlab代码(Application of BP neural network in data prediction and matlab code)

matlab的一些优化函数说明 我们学校用的。。应该不错(matlab optimization function shows some of our school use. . Should be good)
