代码说明：

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)

说明：不同的相邻分组数目v实现的pts抑制ofdm峰均比的算法,可以仿真出v越大,papr的性能越好(The algorithm of reducing ofdm peak-to-average ratio by pts with different number of adjacent packets v can be simulated that the larger v is, the better the performance of papr is.)

1、产生信号，两个实正弦信号的叠加，幅度分别为2、4、1、3；混入均值为0、方差为1的白噪声。采用自适应滤波器对其进行去噪。 2.产生信号，为两个实正弦信号的叠加，其幅度均为4，混入均值为0、方差为1的白噪声。采用有限脉冲响应法设计一个维纳滤波器估计信号，并求最小均方误差。 3.产生高斯分布的白噪声w(n)，自行给定一个5阶AR模型，让该白噪声通过这个AR模型，得到输出信号x(n），再估计x(n）的AR模型数，比较估计的结果和原来给定的AR模型的参数。(A signal to be generated, the superposition of two real sinusoidal signals, amplitude, respectively 2,4,1,3 mixed with mean 0 and variance 1 white noise. Noising using adaptive filter them. (2) generate signals as a superposition of two real sinusoidal signal whose amplitude was 4, mixed with mean 0 and variance 1 white noise. The finite impulse response method to design a Wiener filter estimate signal, and for the minimum mean square error. 3 Gaussian white noise generated w (n), given a five self-order AR model, so that the white noise through the AR model, get the output signal x (n), and then estimate x (n) the number of AR model, Compare the results and the original estimate given by the AR model parameters.)
