Simulink 仿真环境基础学习的教程文档。对于初学者来说是很好的入门。(Simulink simulation environment based learning tutorial document. For beginners it is a good entry.)

在OFDM系统中，自适应资源分配是很重要的，注水算法是资源分配的经典算法，本程序对注水算法进行了仿真(In OFDM systems, adaptive resource allocation is very important, water resource allocation algorithm is a classic algorithm, the procedure for filling algorithm for the simulation)

利用Matlab生成GPS C/A 码的基带信号。 （1）产生卫星PRN 号码为“5”的一组C/A 码； （2）循环生成25 页的导航数据，GPS 时间可填入一固定的已知数值； （3）生成C/A 码扩频信号，每个C/A 码码片给出4 个采样数据； （4）基带信号采用方波信号，电平为0 和1，占空比为50 ％， 不加入噪声，进一步生成某个特定的中频信号(The baseband signal is generated using Matlab GPS C/A code. (1) generate satellite PRN number " 5" is a set of C/A code (2) loop generates 25 navigation data, GPS time can be filled with a fixed known value (3) generated C/A code spread spectrum signals, each C/A code chip sample data is given 4 (4) a baseband signal using a square wave signal with a level of 0 and a duty cycle of 50 , the noise was not added, and further generates a a specific frequency signal)

冈萨雷斯编写的数字图像处理Matlab版，是Matlab和图像处理的最佳组合(A classical digital image processing books, tells the classic algorithm for digital image processing.)

适合matlab2007应用的时频分析工具箱.(The for matlab2007 application time-frequency analysis toolbox.)

教你任何有效使用matlab，快来试试吧，很有用的(teach you how to use matlab )

BOC调制信号的简介。包括一般BOC信号和AltBOC信号。(About BOC modulation signal. Including general BOC signal and AltBOC signals.)

在程序中用一般的MUSIC方法估计了信号的频谱，从两图中可看出在信号各频率处，频谱的峰值较大，故能明显的与噪声相区别，可在一定程度上避免在信号幅度较小时信号被噪声淹没的情况。(MUSIC method general procedures used to estimate the spectrum of the signal, it can be seen from the two graphs in the signal at each frequency of the spectrum peak larger, and it could be significantly distinguished from noise in the signal can be avoided to some extent a lesser extent, the signal is noise submerged.)
