曲线拟合

解集模型，将一年的径流分解为月径流 程序中含有解释说明(Disaggregate yearly streamflow to monthly streamflow)

说明：  使用MATLAB计算图形不变矩,输入一个待测图形，并判断其类别,找出数值最大者，即判断为此类别(Calculate invariance using MATLAB, input a tested graph and determine its category, find the greatest value for judging the category)

子程序，将QAM符号向量d0_J映射为二进制符号矩阵gry(Subroutines, will QAM symbol vector d0_J the mapping matrix for the binary symbols gry)

Connecting ADC to 8051

D2D场景下，用户位置随机分布，根据信道状态好坏，来选择使用哪一个频谱(Under D2D scenario, the user positions randomly distributed, according to a channel state is good or bad, the spectrum used to which one)

卡尔曼滤波的MATLAB代码，代码注释自带，下载者根据自己问题修改

均匀量化和非均匀量化在性能上存在着显著的差异，这种差异可以用信号通过量化器后的量躁比来反映出来。本程序用曲线表示了理论和实际两个方面下两种量化的量躁比。从而可观察他们的性能上的差别。(There are significant differences with the function between Uniform quantization and non-uniform quantization ,which can be quantified by SNR from the quantizer.This program use the curves to denote the SNR of theory and practical signal.Then we can observe the performance of the differences.)

自适应信号处理，最终的权值矩阵就是滤波器的系数，学习曲线描述其收敛特性(Adaptive signal processing, the final weight matrix is the filter coefficient, the learning curve to describe the convergence properties)

说明：  这是国外一本经典教材附带的程序，通信系统的matlab实现，所含例子丰富(This is a classic foreign materials attached to the procedures, communications systems to achieve matlab contains abundant examples of)
