产生随机比特流 并进行2ASK 2FSK 2PSK 2DPSK调制(Generate random bit stream and make 2ASK 2FSK 2PSK 2DPSK modulation)

英文版书籍，学生版学习matlab的书籍，非扫描版。(English books, student books to learn matlab, non-scan version.)

用MATLAB实现了CT平行束滤波反投影和扇束滤波反投影重建过程，效果良好，其中radon变换的方法采用步长法求解，较新颖。(CT achieved using MATLAB parallel beam filtered back projection and fan-beam filtered back projection reconstruction process, to good effect, in which radon transform method using step method to solve, relatively new.)

用matlab实现的曼彻斯特 BVLsQI编码。50 占空比（可调）。绘制时域波形和频域功率谱密度。结果跟北邮的GlxNsvt 的通信原理课件上的形状一模一样。 . (With Manchester BVLsQI encoding matlab realize. 50 duty cycle (adjustable) . Draw time-domain waveform and frequency domain power spectral density. Results with BUPTGlxNsvt Exactly the same shape Wenbin communication on the principles of courseware. )

说明：  径向基函数神经网络的优点：逼近能力，分类能力和学习速度等方面都优于BP神经网络，结构简单、训练简洁、学习收敛速度快、能够逼近任意非线性函数，克服局部极小值问题。原因在于其参数初始化具有一定的方法，并非随机初始化。代码为RBF的matlab程序，可以使用但是需要自己配置数据。(Radial Basis Function Neural Network (RBF-NN) has the advantages of better approximation ability, classification ability and learning speed than BP Neural Network (BP Neural Network). It has simple structure, simple training, fast learning convergence, and can approximate any non-linear function to overcome the local minimum problem. The reason is that its parameter initialization has a certain method, not random initialization.)

在进行利用蒙地卡罗方法进行期权定价的时候，我们有很多减小方差的方法，下面是其中的两种。(During the use of Monte Carlo methods for option pricing, we have a lot of variance reduction method, the following two.)

基于反演设计的位置跟踪matlab实现，可以精确的跟踪位置信号(Backstepping design based on the position tracking matlab realize, you can track the precise location of the signal)
