本人写的中值和均值滤波的代码，主要用于SAR成像滤波，希望管理员给予通过(I wrote the median and mean filtering code, mainly for SAR image filtering, administrators hope to give through)

说明：  非线性有限元程序，二维， 非常好用的啊！！！！！！！！！！！！！！！！！！！！！！！！！！！！(nonliear fem)

该仿真研究了采用相关器进行多谱勒估计的方法，并研究了多普勒失配对相关器检测性能的影响(The simulation study of the correlator for Doppler estimation method, and studied the influence of the Doppler mismatch detection performance)

通信系统的自适应均衡器，能够恢复失真的PSK信号(Adaptive equalizer communication system, a PSK signal to recover distorted)

有限元方法，matlab实现，数值方法，解答详细。(Finite element method, matlab realize, numerical methods, detailed answer.)

本代码是《通信信号处理》课程的大作业相应的代码。主要是通信信号发射端的仿真，具体功能是：1. 产生任意长度的伪随机序列，将序列映射为I,Q两路的信号，2.均方根升余弦滤波器成型. 3.经过通带衰减为3dB的倾斜滤波器（模拟信道衰落效果）4.插零，半带滤波器升抽样。 5.NCO处理单元调制(This code is communication signal processing courses corresponding to the large code. Mainly is the simulation of the communication signal transmitter, the specific functions are: 1. Produce arbitrary length of the pseudo-random sequence, the sequence mapping for the I, Q two-way signal, 2. Raise the root-mean-square filter forming 3. After passband attenuation 3dB tilt filter (analog channel fading effect) 4. Insert zero, half-band filter l sampling. 5. NCO processing unit modulation)

说明：  在matlab中，以simulink为主要工具介绍了系统仿真方法与技巧，包括连续系统、离散系统、随机输入系统和负数系统的仿真。(In matlab in order to simulink introduced as the main tool for system simulation methods and techniques, including continuous systems, discrete systems, stochastic systems and the negative input of the simulation system.)

自己的数字信号处理第三版的课后实验作业，有兴趣的可以参考参考。(Its own digital signal processing of the third edition of the after-school lab assignments, who are interested can refer to reference. !)
