龙贝格积分，MATLAB程序，计算方法作业，内有说明(Romberg integration, MATLAB procedures, calculation methods work, there are instructions)

说明：  使用快速傅里叶逆变换，分析离散时间信号中频率分辨率和信号的样本数之间的关系，并通过不同的滤波器进行对比。(The relationship between the frequency resolution and the number of samples in the discrete-time signal is analyzed by using the inverse fast Fourier transform, and compared by different filters.)

海杂波的matlabb仿真，希望对大家有用 (Matlab simulation of sea clutter, iin the hope that useful to everybody )

利用matlab画出smith圆图，方便分析观察和作图.很好用(Using matlab to draw Smith chart, convenient analysis observation and drawing )

实现卷积编码和相应的维特比译码（卷积码编码器为（2，1，3），维特比译码针对第1、3位模二加和第1、2位模二加）(Convolutional coding and the corresponding realization of Viterbi decoding (convolutional code encoder for the (2,1,3), Viterbi decoder bit mode for the first 1,3 and 1,2 position two plus two plus model ))
