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)

function ber_ml=Alamoudi(snr,soglia) This function simulates a Alamouti scheme. The input variables are soglia and snr. Soglia: is the number of errors after which the iterations stop. For better results, put high value of soglia, but the simulation is longer. snr: the signal to noise ratio (if u don t know what is a signal to noise ratio, well, come back to your high school!). Note: U should use this function with a main function in wich u chose different value of snr. That s because this function work just with one value of snr. If u have problem with this code, write me at m.allegritti@email.it. Take care! Max

这是张小飞的阵列信号的全部MATLAB代码
说明：传统的高分辨波达方向（DOA）估计算法中，一般都假设信号位于远场，此时入射到阵列的信源波前为平面波前，空间信号的定位参数可由DOA来确定。然而，当信源处于阵列的Fresnel区域时，信号波前需用球面波来描述，每个信源的定位信息要用DOA和距离联合描述。因此，远场情况下的一些线性理论推导已不再成立，传统的远场算法的估计不再适用(In traditional high resolution direction of arrival (DOA) estimation algorithms, it is generally assumed that the signal is located in the far field, where the source wavefront incident to the array is plane wavefront, and the location parameters of the spatial signal can be determined by DOA. However, when the source is in the Fresnel region of the array, the wavefront of the signal needs to be described by spherical wave, and the location information of each source needs to be described by DOA and distance. Therefore, some linear theoretical deductions are no longer valid in the far-field case, and the estimation of the traditional far-field algorithm is no longer applicable.)
