SAR雷达基本信号处理算法，包含fft,crange等16个文件，对初学者对SAR雷达的理解有很大的帮助(SAR basic radar signal processing algorithms, including fft, crange such as 16 documents, for beginners to understand the SAR radar very helpful)

离散形式的傅里叶变换可以利用数字计算机快速的算出(其算法称为快速傅里叶变换算法(FFT)).(Discrete Fourier transform can be calculated using a fast digital computer (the algorithm is called fast Fourier transform algorithm (FFT)).)

利用小波算法进行图像和视频处理，将原始小波块放在新小波块的左上角，在小波块右下角补零。(Using wavelet algorithm for image and video processing, the original wavelet wavelet block block on the new upper left corner of the block in the lower right corner of the wavelet zeros.)

This matlab code describes soft demapper (soft bit) for different modulation types: BPSK, QPSK, PSK 8, QAM 16, QAM 64, which are considered for turbo encoding/decoding. And simulation results are also presented.

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.)

说明：  这是一个快速的三维图像双边滤波的实现。这个过滤器平滑图像的同时保留边缘，但在其最直接的实现是非常计算的要求，特别是对大型3D图像。快速双边滤波是一种近似技术，极大地提高了计算速度。我的实现严格遵循Matlab版的快速二维滤波器，只是做了一些修改(This is an implementation of fast bilateral filtering for 3D images. This filter smoothes the image while preserving edges, but in its most straightforward implementation is very computationally demanding, especially with large 3D images. Fast bilateral filtering is an approximation technique which drastically improves the speed of computation. My implementation closely follows the Matlab version of the fast 2D filter with some modifications)
