小区初搜为GSM系统中的一个关键过程，本程序为GSM小区初搜过程的第二部，查找同步突发sch并定时的matlab程序，输入数据由采样数据得到，在转换成所需格式后进行处理。若其中包含sch,则输出找到信息，并计算得到定时信息。若没有，则查找下一个突发。内付算法详细说明文档(Area early in the search for the GSM system, a key process, the procedures for the GSM cell the second part of the beginning of search process to find the synchronous burst sch and timing matlab procedures, input data from the sampling data in converted into the required format for processing. If one includes sch, then output to find information and to calculate timing information. If not, then find the next emergency. Pay the algorithm in detail within the document)

非线性曲线拟合是已知输入向量xdata和输出向量ydata，并且知道输入与输出的函数关系为ydata=F(x, xdata)，但不知道系数向量x。今进行曲线拟合，求x使得输出的如下最小二乘表达式成立： min Σ(F(x,xdatai)-ydatai)^2(Nonlinear curve fitting is a known input and output vectors xdata vector ydata, and know the relationship between the input and output functions for ydata = F (x, xdata), but do not know the coefficient vector x. As least-squares curve fitting expression today, find x such that the output of the establishment: min Σ (F (x, xdatai)-ydatai) ^ 2)
