阵列天线时TD_SCDMA系统信道估计性能的新型改进(Array antenna system, the channel estimation performance TD_SCDMA New Enhanced)

扩频通信的相关仿真文件，希望有帮助，：）(Spread Spectrum Communication Simulation related documents, hoping to help :))

AFSA_fxy是用人工鱼群算法（artificial fish swarm algorithm）解决二元函数寻优问题。文件打开后运行AFSA_fxy.m文件即可得到结果，代码中有详细注释，方便修改。运行示例已经保存为图片附在压缩包中。(AFSA_fxy is (artificial fish swarm algorithm) to solve the optimization problem with a binary function AFSA. Run AFSA_fxy.m file to get the file to open the result, the code has detailed notes, easy to modify. Run the sample has been saved as a picture attached to the compressed package.)

用MATLAB对给定信号做短时傅里叶分析 用MATLAB对给定信号做短时傅里叶分析(Using MATLAB for a given signal the short time Fourier analysis Using MATLAB for a given signal the short time Fourier analysis)

说明：  K近邻算法（KNN）的matlab源代码，程序清晰易读(K neighbor algorithm (KNN) of matlab source code, and the program is clear and easy to read)

4. 数字信道化抗干扰反正，首先数字信道化多相滤波，差值的倍数为信道数的两倍，再采用AGC技术抗干扰。(4 digital channel anti-jamming anyway, the first digital channel of the polyphase filter, the difference in multiples of twice the number of channels, and then using the AGC technology anti-jamming.)

元胞自动机程序模型，用来研究和分析随时间节点变化，元宝状态的程序！(cells automatic，)

神经网络，它是一种模范动物神经网络行为特征，进行分布式并行信息处理的算法数学模型。这种网络依靠系统的复杂程度，通过调整内部大量节点之间相互连接的关系，从而达到处理信息的目的。(Neural network, it is a neural network model of animal behavior characteristics, the distributed parallel algorithm for information processing model. This network relies on the complexity of the system, by adjusting the connection between the number of nodes within the relationship, so as to achieve the purpose of processing information.)

换能器导纳图绘制函数，需要自备换能器导纳数据，代入即可(Transducer admittance mapping function, you need to bring their own transducer admittance data can be substituted into)
