Introduction Fiber-to-the-Premises solutions today vary from high-bandwidth, symmetrical and dedicated fiber Ethernet-to-the- Home (ETTH), to traditional TDM PON, such as Gigabit PON (GPON), solutions that are asymmetrical, share bandwidth among users and are not flexible nor scalable to address various residential requirements and enterprises in one infrastructure.

MATLAB二分法程序， ！！！！(MATLAB二分法程序)

主要功能是对数据进行自相关处理，然后通过带通滤波后进行解调，得到数据的主要特征。(The main function is to carry on the data correlation processing, and then through the band-pass filter after demodulation, get the main features of the data.)

永磁同步电机矢量控制，三环闭环，空间矢量调制(Permanent magnet synchronous motor vector control, tricyclic closed-loop, space vector modulation)

说明：  利用IIR滤波器设计一个低通滤波器，能够分析到电力系统中的三次谐波，要求满足如下指标：截止频率150HZ，阻带衰减≥30db(IIR filter design using a low-pass filter, to analyze the power system in the third harmonic, the requirements to meet the following indicators: cut-off frequency 150HZ, stopband attenuation ≥ 30db)

SLNR下，信噪比和误码率的关系,涉及了两域联合(SLNR, the relationship between SNR and bit error rate, involves a two-domain joint )

聚类算法，不是分类算法。分类算法是给一个数据，然后判断这个数据属于已分好的类中的具体哪一类。聚类算法是给一大堆原始数据，然后通过算法将其中具有相似特征的数据聚为一类。这里的k-means聚类，是事先给出原始数据所含的类数，然后将含有相似特征的数据聚为一个类中。所有资料中还是Andrew Ng介绍的明白。首先给出原始数据{x1,x2,...,xn}，这些数据没有被标记的。初始化k个随机数据u1,u2,...,uk。这些xn和uk都是向量。根据下面两个公式迭代就能求出最终所有的u,这些u就是最终所有类的中心位置。(Clustering algorithm, not a classification algorithm. Classification algorithm is to give a figure, and then determine the data belonging to a specific class of good which category. Clustering algorithm is to give a lot of raw data, and then through the algorithm which has similar characteristics data together as a class. Here k-means clustering, is given in advance the number of classes contained in the raw data, then the data contain similar characteristics together as a class. All information presented in or Andrew Ng understand. Firstly, raw data {x1, x2, ..., xn}, the data is not labeled. K random initialization data u1, u2, ..., uk. These are the vectors xn and uk. According to the following two formulas can be obtained final iteration all u, u is the ultimate all these classes the center position.)
