Simulation of SAR radar echo. Posibility to change sampling time, number and place of reflecting points and position of radar platform.

这是一个关于基于互信息的图像配准程序，是以matlab编写(This is a mutual information based image registration procedures, the preparation is matlab)

说明：  6. 在三条径的瑞利信道中，对于OFDM： (1) 请设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK调制时的误码率性能。画出比特信噪比与信道估计均方误差的关系曲线，画出比特信噪比与误码率的关系曲线。 (2) 设频率已同步，请设计OFDM一种具体的采用循环前缀进行时间同步方法，用Simulink进行仿真，画出比特信噪比与捕获概率的关系曲线。 (3) 设时间已同步，请设计OFDM一种具体的采用循环前缀进行频率同步方法，用Simulink进行仿真，画出比特信噪比与频率同步误差的关系曲线。 (。 6 In the three path Rayleigh channel for OFDM: (1) Please design a specific guide-assisted channel estimation method, the Simulink simulation, BPSK modulation measuring the bit error rate performance. Draw-bit signal to noise ratio and channel estimation mean square error curve, draw-bit signal to noise ratio and bit error rate curve. (2) set the frequency has been synchronized, the design of a specific OFDM cyclic prefix used for time synchronization method, the Simulink simulation, draw-bit signal to noise ratio and capture probability curve. (3) set time has been synchronized, the design of a specific OFDM cyclic prefix used for frequency synchronization method, the Simulink simulation, draw-bit signal to noise ratio and frequency synchronization error curves.)

求1000以内的水仙花数(例如：一个数是abc，如果abc=a*a+b*b+c*c,那么abc就是水仙花数)(For less than 1000 of the number of daffodils (for example: a number is ABC, if abc=a*a+b*b+c*c, then ABC is a daffodil number) )

多种esprit算法的对比仿真分析，通过对比，可以知道哪种算法最适合(Contrast variety esprit algorithm simulation analysis, by contrast, can know what the most appropriate algorithm)

说明：  基于tms5402的 AD转换程序 有项目工程和源程序(Tms5402 based on the AD conversion process and project source code)

1. Extract files and run Audio_denoise_main.m file folder... 2. Click on Load & play Audio file and Original sound.wav file 3. Then using slider AWGN (White gauusion noise)...it is vary 1 to 10 set it to 10.. 4. now click on Add Noise and play... 5. u can save noisy signal by save noisy signal tab... 6. now wavelet... 7. thresholding.. 8. now click on Denoise and play....wait for some time...this will take 25 sec time 9. now save that denoised signal...and record all output parameters... 10. now click on clear all and exit
