产生均匀分布的随机白噪信号,并观察数据分布的直方图产生均匀分布的随机白噪信号,并观察数据分布的直方图(Generate uniformly distributed random white noise signal, and to observe the distribution of the histogram data generated uniformly distributed random white noise signal, and to observe the data distribution histogram)

本段代码主要是为了实现讲多光谱图像进行光谱分离然后再合并成一种可以在matlab中显示的格式.tif的图像，同时保证了原始的图像信息不丢失(This code is mainly to achieve multispectral images speak for spectral separation and then combined into a format that can be displayed in matlab. Tif image, while maintaining the original image information is not lost)

仿真了用于MIMO雷达的OFDM Chirp波形的自相关函数和互相关函数，便于进一步优化OFDM Chirp波形，使互相关和自相关性能接近正交波形的性能，从而提高雷达目标检测性能。因为匹配滤波相当于一个互相关器。附有所仿真波形的参考文献，波形设计见本人之前上传的文件(this matlab program simulate the correlation function of ofdm chirp waveform,so that reader can optimizing design new ofdm chirp waveform.from the simulation results we see that the correlation performance are not well enough,so we have to optimize the ofdm chirp.there is reference of my simulation.)

根据有无固定基础设施，无线局域网又可分为BSS (Basic Service Set)和IBSS (Independent Basic Service Set)。我们要研究的ad hoc网络属于后者。假设在一个ad hoc网络中，移动节点的发射功率PTx总是恒定的。要发送数据的移动节点总是先监听信道，测量接收到的信号功率X，其中X= I + N, I为接收到的干扰，N是噪声。移动节点只有在X＜INThre时，才可以发射。式中，INThre为背景噪声门限。 在仿真中，我们规定每个移动节点的发射功率是常数，PTx = 1W；接收节点接收机的灵敏度Smin = -80 dBm；信号质量 min = 2 dB；系统的背景噪声门限INThre = 1.2e-10。 (According to the availability of fixed infrastructure, wireless local area network can be divided into BSS (Basic Service Set) and IBSS (Independent Basic Service Set). We have to study the ad hoc network belong to the latter. Assuming in an ad hoc network, mobile node s transmission power is always constant PTX. To send data to the mobile node always monitor channel, measuring the received signal power X, which X = I+ N, I was received interference, N is the noise. Mobile node only when X <INThre when it is fired. Where, INThre threshold for background noise. In the simulation, we require that each mobile node s transmission power is constant, PTx = 1W receiver node receiver sensitivity Smin =-80 dBm signal quality )
