代码说明:

资源描述function [Reserve,Remove] = OutlierRemoval ( Input ) %用于剔除LiDAR中的粗差点 %Input[X,Y,Z,....]  Output为删除Input粗差点所在行 %算法思想:第一步,以0.1米为间隔对整个高程范围分段,分别统计各高程段LiDAR点数目,频数小于限差的点为粗差点 %第二步,对整个平面区域格网化,格网大小为1/sqrt(n),n每平米点数;格网化后计算每个格网内平均高程,每个LiDAR %点高程与所在格网平均高程之差求均值和方差,距均值三倍方差之外的点判定为粗差点。

    本文提出一种联合盲自适应梯度算法的功率控制算法,该算法同时对功率向量和接收滤波器权向量进行迭代更新。仿真结果表明,采用本文提出 的功率控制算法, 在系统内用户发射总功率一定的条件下, 可以获得更高的用户信干比和更大的系统容量。(Throughout the monograph, we highlight the use of mathematical language and tools in the study of power control, including optimiza- tion theory, control theory, game theory, and linear algebra. Practical implementations of some of the algorithms in operational networks are discussed in the concluding chapter. As illustrated by the open prob- lems presented at the end of most chapters, in the area of power control in cellular networks, there are still many under-explored directions and unresolved issues that remain theoretically challenging and practically important.)

  • 声音识别matlab
    本代码针对正常非正常开门(指盗窃开门等声音)的声音进行识别的问题,通过matlab的sound和plot采集到了正常和非正常开门的声音信号和声音波形图,附件中有正常开门声音(如正1.mat),非正常开门声音(如非1.mat),各40次开门,共80次开门声音数据。将这些数据利用matlab的load函数载入到计算机内存,内存中变量有Fs和y等变量,其中Fs为采用频率,y为采用数据,通过建立数学模型将函数关系表示出来,并利用合适的时域或(和)频域特征表达声音信号,建立出特征向量.
