主动轮廓编码，用于交流学习，对一些图像分割不准确的轮廓进行进一步寻找准确轮廓(just for article，we can use it to do much work about image segementation)

this is a folder containing algorithms and source codes for face recognition

线性调频信号不同时宽带宽积情况下频域分析及作图(Linear FM signal is not under the same time bandwidth product frequency domain analysis and graphing)

相空间重构源代码，可以直接调用，用于混沌理论(Phase space reconstruction of the source code, you can directly call for chaos theory)

IIR滤波器的设计，基于matlab的脉冲响应不变法和双线性变换法设计IIR滤波器(IIR filter design)

LTE下行链路发射分集仿真，仿真配置：16QAM调制、1/3码率Turbo编码、10MHz带宽、每个子帧一个PDCCH符号、单码字、8次迭代Turbo译码，每次处理1000万比特用户数据、早期终止机制、MMSE（最小均方误差）MIMO接收器，PDSCH发射端进行发射分集预编码。信道模型是LTE-MIMO信道附加AWGN信道。收发两端采用的双天线配置，天线相关性为中等。(LTE downlink transmit diversity simulation configuration: 16QAM modulation, 1/3 Turbo coding rate, 10MHz bandwidth of each sub-frame a PDCCH symbol, single code word, 8 iterations Turbo decoding, each processing 10 million bits of user data, early termination mechanisms, the MMSE (minimum mean square error) the MIMO receivers, a PDSCH transmitting terminal transmit diversity precoding. Channel model is LTE-MIMO channel additional AWGN. Dual antenna transceivers at both ends of the configuration, the antenna correlation is moderate.)

说明：  分布式编码代码 C语言的，很多行，如果要用Matlab编应该有些参考价值。(distributed coding)

（1）离散余弦变换DCT基底灰度图像绘制（2）离散傅里叶变换DFT基底灰度图像绘制((1) discrete cosine transform DCT base gray image rendering (2) Discrete Fourier Transform DFT basal gray image rendering)

图像处理基础算法源代码MATLAB集合，里面很多修改就可以用(Image Processing MATLAB based algorithm source code set, which can be used to modify many)

说明：  矩阵LDLT分解与Cholesky分解 求矩阵A=（αij）20x20的LDLT分解与Cholesky分解(Matrix LDLT decomposition and Cholesky decomposition Matrix A = (αij) 20x20 of the LDLT decomposition and Cholesky decomposition)
