FHSS_DSSS_CDMA

这是一个OFDM系统的信道估计仿真MATLAB，分析了基于训练序列的估计方法(This is an OFDM system channel estimation simulation MATLAB, analysis of the estimation method based on training sequence)

single user energy detection

本实验程序用于计算信号的包络和包络信号的频谱（包络谱）。 算法采用了Hilbert变换计算包络( This experiment is used to calculate the envelope (envelope) of the envelope and envelope of the signal. The algorithm uses a Hilbert transform to compute the envelope)

本文件对PID参数kp,ki,kd进行寻优，以ITAE作为指标函数。 PSO 文件中有详细的参数设置和寻优过程 GA寻优与PSO寻优作为对比出现 figure1展示了随着迭代次数的变化，适应度函数的收敛情况 figure2展示了kp,ki,kd的迭代情况 ht 文件是用来画图的 问题解决思路.pdf 简要介绍了粒子群算法寻优的过程(In this document, the PID parameters KP, Ki, KD are optimized, and ITAE is used as the index function. PSO file has detailed parameter settings and optimization process GA optimization and PSO optimization as a contrast appear Figure1 shows the convergence of fitness function as the number of iterations changes Figure2 shows the iterations of KP, Ki, and KD The HT file is used for drawing The problem solving idea.Pdf briefly introduces the process of particle swarm optimization)

bilateral filtering code

使用吗matlab语言，实现很多模式识别上的经典算法，如Perceptron_Batch算法等(Matlab language to use it to achieve many of the classic pattern recognition algorithms, such as algorithm Perceptron_Batch)

说明：  把I、Q 两路信号分别作FFT ,找出频域内信号的幅度,即可算得两路分量的幅度一 ％致性 把I、Q两路信号合成一个复数信号,作FFT ,对得到的频谱求镜像抑制比。(The I, Q signals, respectively, for the two FFT, to identify the range of frequency domain signal can be considered two-way range of 1 weight of the letter I, Q synthesis of two-way signal a plural signal for FFT, to obtain the spectrum for image rejection ratio.)

简单的阐述方式，可使读者尽快掌握要领。主要介绍了一些编程语句的使用方法。(A simple exposition of way, will enable readers to quickly grasp the essentials.It introduces a number of programming statements used.)

Matlab - DC-Shunt Generator

说明：  四阶超混沌系统的lyapunov指数计算程序。(Lyapunov exponent calculation program for fourth-order hyperchaotic systems)
