用vi传输矩阵法研究均匀布拉格光栅的传输特性(Uniform Bragg grating transmission characteristics of the transfer matrix method with vi)

用matlab所撰寫的huffman code,裡面沒有使用matlab內建的函示,完全自己撰寫而成,使和初學者練習參考使用.(Using matlab written huffman code, which did not use the matlab built-in letter that is entirely their own written so that beginners practice and their use and reference.)

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)

说明：  小波阈值去噪的软硬阈值去噪算法，里面包含了软硬阈值不同的去噪效果，大家一起学习哈(Hard and soft wavelet threshold denoising threshold denoising algorithm, which includes hard and soft threshold denoising different effects, we will study together and Kazakhstan)

阵列信号处理，自适应波束形成，Capon算法(array signal processing，adaptive beam forming，Capon)

matlab时频分析工具箱时频分析工具箱time-frequency analysis toolbox 第二代，比第一代增加了许多信号处理的函数，有些函数进行了功能的增进。使用的时候，解压到MATLAB安装目录的toolbox目录下，并在matlab中将其添加到搜索路径中使用。(time-frequency analysis toolbox matlab second generation than the first generation adds many signal processing functions, some functions have been enhancing features. Use it, extract it to MATLAB installation directory toolbox directory and search paths to work.)

The model used for creating the reference voltage is shown in Fig. 4. First, photovoltaic output current (Ipv) and output voltage (Vpv) are passed through a first order low pass filter with a magnitude of G = 1 and a time constant of T = 0.01 seconds in order to filter out the high frequency components or harmonics from these signals as shown in Fig. 5 and Fig. 6. The filtered current and voltage signals (Ipv_F and Vpv_F) are then fed into the MPPT control block that uses the Incremental Conductance Tracking Algorithm. An algorithm that is based on the fact the slope of the PV array power curve shown in Fig. 7 is zero at the Maximum Power Point (MPP), positive on the left of the MPP, and negative on the right. The MPP can thus be tracked by comparing the instantaneous conductance (I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):
