MATLAB-Numerical-integration

利用DCT变换进行图像压缩的小程序，也是我的第一个matlab程序(For image compression using DCT transform a small program, but also my first one matlab program)

说明：  hht程序代码，小波变换，对比分量的功率谱密度函数图，找出最优小波(hht code, wavelet transform, as compared with the weight of the power spectral density function map to find the optimal wavelet)

Conjugate gradient method

说明：  信号子空间变换算法(SST)的聚焦矩阵是利用各频率点与参考频点之间信号子空间的关系导出的.(The focus matrix of signal subspace transform (SST) algorithm is derived from the relationship between the signal subspace of each frequency point and the reference frequency point.)

In this project, we have designed and implemented a method to estimate the dual frequencies in sinusoids immersed in additive white Gaussian noise. The Cramér-Rao lower bound (CRLB) for the signal model and a nonlinear least square frequency estimator are derived. The estimator is evaluated by numerical examples.

发送端统一使用4根发送天线,通过改变接收天线的数目来比较不同数目的接收天线对空间调制（spatial modulation）系统性能的影响。(Sending uniform use of four transmission antennas, by changing the number of reception antennas to compare the different number of receiving antennas for spatial modulation (spatial modulation) system performance.)

对脑电信号进行小波分解并重构，提取脑电信号不同频段的成分(Decompose EEG and then reconstruct it to get different component)

RS码是一种纠错能力很强的编码，对RS码具有进一步分析(RS code is a very strong error correction coding, with a further analysis of the RS code)

IEEE14节点进行牛顿拉弗逊法计算电力系统潮流计算(IEEE14 node calculates Newtonian Raphson method for power flow calculation)

本文对倒立摆系统的Lagrange方程建模与模糊控制进行了简单介绍(In this paper, the inverted pendulum system Lagrange equation modeling and fuzzy control for a simple introduction)
