用PSO优化LSSVM的参数，得到最优参数，使得分类更加准确。(Using the PSO the LSSVM the parameter, the optimal parameters, more accurate classification. )

线性调频信号的产生线性调频信号的产生线性调频信号的产生(The generation of linear frequency modulation signal )

说明：  LDPC码的matlab实现，把解码的部分改过了，实验过很多次，符合理论要求，码长越长误码率越低(The implementation of LDPC code in MATLAB has changed the decoding part. It has been experimented many times and meets the theoretical requirements. The longer the code length, the lower the bit error rate.)

用matlab程序编写的一个捕捉鼠标坐标的小程序，用来参考。(Matlab programmers use to capture the mouse coordinates of a small program used to refer to.)

说明：  此为C++环境下的LDPC编译码的完整的源代码。常用于通信系统的编译码仿真过程。有助于各种项目的完成。(This is the C++ environment LDPC coding and decoding of the complete source code. Commonly used in the encoding and decoding communication system simulation. Contribute to the completion of various projects.)
