分数阶傅里叶变换 FrFT LFM paraEstimation

为了防止码间干扰，rs码编译码采用硬判决+维特比译码(rs_hdd_vterbi)

说明：  主要包括一些空是编码的代码，对于那些正在研究空是编码的同志，很有用。(Including some of the main space is encoded code, for those who are studying space is encoded comrades, very useful.)

代码介绍matlab中怎么实现C++的编译，附带很多例子，对初学matlab中嵌入C或C++代码，很有帮助！(The code describes how to achieve in matlab compilation of C++, comes with a lot of examples, beginner matlab to embed C or C++ of code, very helpful!)

PID Tunning with PSO

pwelch可以实现matlab中的PSD估计，上传资料为pwelch的code(pwelch matlab can estimate the PSD, upload data to the code pwelch)

BFILTER2 Two dimensional bilateral filtering. This function implements 2-D bilateral filtering using the method outlined in: C. Tomasi and R. Manduchi. Bilateral Filtering for Gray and Color Images. In Proceedings of the IEEE International Conference on Computer Vision, 1998.

FTF自适应算法的MATLAB仿真，包括模型构建、算法流程仿真，以及性能仿真(MATLAB FTF)

distance snaked的matlab实现，用于分割和边缘检测(matlab realize the distance snaked for segmentation and edge detection)

Flexible construction of girth-six QC-LDPC Codes(The program constructs girth-six QC-LDPC codes given row-weight,k, column-weight,j, and sub-matrix size,m. The obtained parity-check matrix is stored in H. The construction has flexibility in that j,k and m can be varied.The program achieves girth-six by applying the row-column constraint. There are m rows in j submatrices. No two rows should share the same column more than once. This constraint is applied to avoid 4-cycles. The construction has flexibility in that j,k and m can be varied.)
