码分多址(CDMA)技术作为第三代移动通信系统的核心技术，具有容量大、抗干扰能力强等优点。然而,传统的CDMA系统属于窄带扩频系统,它的数据速率比较低,不能胜任新一代移动通信系统 （beyond 3G）高速数据通信的需要。而多载波传输技术－正交频分复用（OFDM），作为后三代移动通信的核心技术，则具有高数据速率传输的特点。(Code Division Multiple Access (CDMA) technology as the third generation mobile communication system' s core technology, high capacity, anti-interference ability and so on. However, the traditional narrow-band CDMA system is spread spectrum system, and its relatively low data rate, can not do next-generation mobile communication systems (beyond 3G) high speed data communication needs. The multi-carrier transmission technology- orthogonal frequency division multiplexing (OFDM), after three generations of mobile communications as a core technology, the high data rate transmission characteristics.)

图论中KM算法的源程序，仿真了5个用户5个信道的频谱分配问题(KM algorithm in graph theory of the source, simulation 5 of 5 users of spectrum allocation channel)

symbol synchronization in ofdm

说明：  matlab谱分析工具箱，作谱分析的很有用的工具，是基于matlab7.0的(Matlab Toolbox spectral analysis, spectral analysis for the very useful tool, is based on the matlab7.0)

图切优化算法，通过它可以使得C++程序脱离vc环境在matlab中运行。(Figure cut optimization algorithm, it can makes C++ program from the vc environment in matlab run.)

This folder contains presentation file on electrostatic discharge and its adverse effects.Then this folder contains my matlab final project report and the project title was designing butterworth filters using matlab.Then this folder also contain one main title page that can be used for reports title page after some formating.

matlab程序源码书籍，其中包含多个实例，是个新手学习的不错的书籍，并且包含一个surface用法实例代码(matlab program code book, which contains more than one instance, is a novice learning good books, and contains a surface usage example code)

封装好的模块是PV（光伏电池），本例利用斜坡信号作为电压端输入，仿真出光伏电池的外特性。(The packaged module PV (photovoltaic cells), in this case the use of the ramp signal as the input voltage terminal, simulation of the external characteristics of the photovoltaic cells.)
