用matlab去计算无缺陷的有限周期光子晶体的带隙问题(Using matlab to calculate the defect-free for a limited period photonic crystal band gap problem)

说明：  MATLAB中的混沌系统的分析方法，包括李雅普诺夫指数等等(MATLAB in the analysis of chaotic systems, including Lyapunov exponents, etc.)

Matlab的帧时隙ALOHA防碰撞仿真算法(frame slotted ALOHA is designed and implemented based on Matlab frame slotted ALOHA)

1、本程序用于仿真里德-穆勒（Reed-Muller）码在AWGN信道中的性能，调制采用bpsk 2、理论请参见《差错控制编码》（第二版），Shu Lin（美）编，晏坚等（译）一书P70-75.且仿真结果与书中图4-2完全一致 3、BPSK_AWGN_RM_Code.m为主程序，点击运行即可 4、The_creation_of_RM_code.m和RM_Decode.m分别为RM码的编、译码程序，而Majority_logic_decision.m用于译码中的大数判决，combine_dunction.m用于计算组合数。(1, the procedure for the simulation Reed- Muller (Reed-Muller) codes in AWGN channel performance, modulation using bpsk 2, theory, see " Error Control Coding" (second edition), Shu Lin (America) series , Yan Jian, etc. (translated) book P70-75., and the simulation results consistent with the book Figure 4-2 3, BPSK_AWGN_RM_Code.m-based program, click Run to 4, The_creation_of_RM_code.m and RM_Decode.m were RM compiled code decoding process, and in large numbers for decoding Majority_logic_decision.m judgment, combine_dunction.m used to calculate the number of combinations.)

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

本压缩包包括吸气式高超声速飞行器的纵向刚体仿真模型和弹性体仿真模型。利用s函数编写的simulink模块，然后用MATLAB画出二者的图像进行对比(Nonlinear Longitudinal Dynamical Model of an Air-Breathing)

自己用MATLAB编写dsp5509的中的sine.dat文件，附详细正确的编写方法，和m文件。只要改些参数就可任意生成想要的函数.dat是授人渔的方法，此论坛以及网络流传的函数经试验不好使，没有考虑许多问题生成的文件是错误的，在此详细介绍生成dsp标准.dat方法(Use matlab to creat .dat file for dsp5509 and show the method for other type dsp. It is very useful.)
