Diffusion-k-tensor-Estimation

很好的OFDM仿真程序代码，大家一起分享吧，祝大家分享愉快序，希望对大家有用。(OFDM simulation code well, we share it, I wish to share a happy sequence, we hope to be useful.)

说明：  基于16QAM调制解调的OFDM信道估计，计算了不同信噪比下的误码性能曲线，并画出了图。(Comb based on the OFDM pilot channel estimation, calculation of the BER performance under different signal to noise ratio curve, and draw the map.)

此段代买可以用来实现层次分析法，通过输入参数、更改参数，利用循环自动检验是否符合层次分析法的要求(solve the AHP problem)

针对智能车路径规划的问题，采用人工势场法进行智能车的路径规划，进而为智能车提供一条安全无碰的较优路径。本程序基于源程序进行了改动，松弛了迭代终止条件，避免智能车绕过目标无限探测下去。(Smart car for path planning problem, the use of artificial potential field of intelligent vehicle route planning, thereby providing a safe path for the optimum touch smart car. The program is based on the source code made changes, relaxation iteration termination conditions, avoid detection infinitely intelligent car rounded the target down.)

说明：  一个自己写的节点导纳矩阵生成程序，不同的小程序完成不同的功能(A self - written node admittance matrix generation procedures)

该程序用于多普勒频率估计，可以估计多普勒模糊数与基带多普勒频率，从而得到解模糊情况下的多普勒频率，算法基于IEEE文章提出的wavelength diversity 算法所写的。(This programme is used to resolve the absolute doppler frequenc without doppler ambiguity.The algorithm is based on the wavelength diversity idea proposed by the IEEE paper.)

说明：  这是一个基于ofdm的系统的调制解调的matlab程序(This is a ofdm modem program)

摘　要:针对茄子图像的灰度和颜色特点,利用MATLAB中丰富的图像处理函数,分别进行了色差分割和色调分割。在 色调分割中,采用了自动选取阈值的Otsu法。在去除残留噪音的处理中,采用标注的方法对二值图像的各连通区域进行面积 统计。保留最大面积的区域,从而使分割效果大大改善。利用多参数来衡量分割效果,使评价做到最大程度的客观、合理。(Based on the gray- level and color characteristics of eggp lant image, hue and color- difference segmentation were conducted by using the rich image p rocessing functions embedded inMATLAB. The auto threshold- adap tivemethod ofOtsu operation was specially used for hue segmentation. And upon the elimination of the residue noise, labelingmethod for statistical calculation was introduced for the connected regions of the binary image. Themaximum areaswere p reserved to imp rove segmentation effects. In addi2 tion, multi- indiceswere app lied to assess the effect of segmentation, in order to get impersonal and reasonable assessment)
