生成圆锥共形阵阵元位置，改变顶角，圆锥高度，阵元间距(Generate the position of conical conformal array elements, change the apex angle, the height of cone and the spacing of array elements)

说明：  用MATLAB产生线性跳频信号，中心频率和带宽可调(Using MATLAB to generate linear frequency hopping signal with adjustable center frequency and bandwidth)

说明：  标准化降水蒸散发指数 matlab的代码(Standardized index precipitation evaporation for matlab)，直接按照例子中的数据格式运行SPEI_Cal.m文件，运行结果在stacking中查询，可以自己修改时间尺度，亲测可用。(The program calculates a time series of the Standardised Precipitation- Evapotransporation Index (SPEI) at a given time interval from an input data file containing monthly time series of precipitation and mean temperature, plus the geographic coordinates of the observatory.)

根据深圳市出租车GPS数据所提供的信息，针对交通出行数据的空间分布特征，选取了4月18号这天的全天数据出租车载客后的行驶数据， 利用mtalab对数据的处理，筛选出出租车的起始点及拥堵的时段的行驶数据并通过kmeans聚类分析设定拥堵的标准，得到对于出租车在路段上的车速在小于2.15公里/小时的时候可以认为非常拥堵，拥堵的时段 5:00-7:00,12:00-14:00,19:00-21:00，非常拥堵的时间段为5:00-7:00，19:00-21:00。(analyse traffic jam status of the shenzhen city)

c语言编写的DSP程序，实现ARMA功率谱估计。(c language of the DSP program, to achieve ARMA power spectrum estimation.)

本文提出在数字移动通信中子带滤波器组处理可以提高不同阵元信号的相关性,从而能改善自适应阵列抑制码间干扰(ISI)和共信道干(In this paper, it is proposed that the correlation of different array element signals can be improved by processing the subband filter banks in digital mobile communication, thus the adaptive array suppression inter-symbol interference (ISI) and the co-channel stem can be improved.)
