FIR低通滤波器设计,表达得还比较详细，可以借鉴参考(FIR low-pass filter design, is also expressed in more detail, you can learn from the reference)

matlab中的mimo仿真源代码，欢迎下载使用(Simulation of MIMO matlab source code, welcome to download)

用于文本语义分析的潜在语义分析算法LSA(Latent Semantic Analysis)，包含详细的函数说明，原理分析及数据。相比原来版本的LSA，增加了文件demo.m以增加可视化效果，更有利于读者使用。(-Semantic Analysis for Text of Latent Semantic Analysis Algorithm LSA (Latent Semantic Analysis), contains a detailed description, principles of function analysis and data. Run demo.m can see the visualization effect.)

彩色图像的各种阈值去噪处理，对各种阈值去噪进行编程比较。(All sorts of color image processing, threshold denoising of various threshold denoising program.)

this function perform huffman coding and decoding on image by using matlab program ..

有关OFDM信号检测与估计的一篇文章，是IEEE上的，有需要的下！！(The OFDM signal detection and estimation of an article is on the IEEE there is a need for the next! !)

This is the PAPR simulator for SC-FDMA by using the Raised-cosine filter or Root raised-cosine filter under different rolloffFactor.

关于粒子群算法的相关论文，共有文章17篇，可供有兴趣的朋友研究讨论(Particle Swarm Optimization on the relevant papers, a total of article 17, interested friends for study and discussion)

说明：  用于计算公路铁路施工中的缓和曲线的计算!(Used to calculate the railway and highway construction in the calculation of Curve!)

使用矩形窗函数，分析信号截短对离散傅立叶变换的影响，其中原始信号为正弦函数(Use a rectangular window function, the analysis of the signal truncated discrete Fourier transform, which the original signal is a sine function)
