matlab processing and realization of the voice, very useful

基于matalab的信道自适应均衡技术研究(Matalab based channel adaptive equalization technology research)

基本粒子群程序，可以给急需的人提供些帮助。 (Of the particle swarm program)

在matlab上运用有限时域差分法模拟二维光子晶体(the simulation of tm mode in two-dimensional photonic crystals using FDTD)

本程序是对遗传算法的改进实现，在遗传操作中的选择 复制 交叉部分做了改进。代码调试通过 可以通过宏命令修改迭代次数。(This program is the improvement of genetic algorithm implementation, the choice of operation in the replication of genetic cross-section are improved. Debugging through macro commands can be modified by the number of iterations.)

MAF小程序，对初学者有一定帮助。MATLAB编写(MRF MATLAB)

An electric meters are used everywhere to calculate the consumption of power. Wireless meter reading technology can save human resources and another feature of this kind of meter is, it improve the accuracy since it works on real time application, enabling management sector to access to data messages within a short period of time and accurately. Due to its wireless communication network, it just not save human and material resources but this property leads to most economical meter in terms of investment. In this paper, power consumed by the consumer is monitored by base stations through wireless network. It aims to reduce the man power for billing since the meter reading is transmitted through ZigBee and at base stations we calculate bill, save records of consumers. The most important part of this project is that we can monitor any fault in meter as well as any tempering which is used to steal the electricity.

： 正交频分复用( O F D M) 是第四代移动通信的核心技术。 该文首先简要介绍了O F D M基本原理， 重点研究了理想同步情 况下， 保护时隙( c P )和不同的信道估计方法在高斯信道和多径瑞利衰落信道下对O F D M系统性能的影响。 在给出O F DM系 统模型的基础上， 用 MAT L A B语言实现了整个系统的计算机仿真并给出参考设计程序。 最后给出在不同的信道条件下， 保 护时隙、 信道估计方法对 OF DM系统误码率影响的比较曲线， 得出了较理想的结论。 关键词： 正交频分复用； 仿真； 循环前缀； 信道估计(good)

基础学习，可以实现编码的基础学习，认真学习还是可以学很好的(Based learning, can achieve coding based learning, serious learning can still learn a good)

matlabde的一些东西大家可以下下看啊(matlabde some things we can look at under ah ha ha)
