OFDM-MATLAB
首先根据短训练字的特性进行相关运算,进行信号到达检测,当检测到相关值大于门限一定次数后,认为有信号到达。然后根据长训练字的特性,进行相关运算,进行OFDM符号FFT窗口起始位置的估计。估计出FFT窗口的位置后,先在时域进行小频偏的估计,将两个长训练字进行小频偏补偿后,进行FFT运算,根据FFT运算的结果进行整数倍频偏的估计。这些参数估计完成后,就可以进行数据解调了。先对数据部分进行完整的频偏补偿,然后根据估计的FFT窗口位置进行FFT运算得到频域的数据,进行解调。然后在对应于导频的子载波位置上提取出导频信息,根据导频信息估计出剩余定时误差以及剩余的信道响应误差,将误差量送入环路进行跟踪。当收到所有数据后,重新回到信号到达检测状态,进行下一次信号到达的检测和信号接收。(failed to translate)

Fyzzy logic controller
模糊逻辑控制器的谐波最小化。出现了给用户提供优质电能的问题。这是由于网络中非线性负载的增加,构成了电网的谐波污染源,产生了许多干扰,干扰了电气设备的优化运行。本文提出了消除非线性负载引入的谐波的解决方案。利用Matlab Simulink对有源电力滤波器(APF)在稳态和暂态过程中对非线性负载产生的谐波和无功功率进行了补偿和分析。仿真方法对有源电力滤波器的实用性得到了证明,利用MATLAB SIMULINK具有更好的电能质量洞察力,以开发基于有源电力滤波器的新型模糊逻辑控制器(This is due to the increasing presence in network of nonlinear loads.They constitute a harmonic pollution source of the network, which generate many disturbances, and disturb the optimal operation of electrical equipments. This work, proposed a solution to eliminate the harmonics introduced by the nonlinear loads. It presents the analysis and simulation using Matlab Simulink of a active power filter (APF) compensating the harmonics and reactive power created by nonlinear loads in steady and in transients. The usefulness of the simulation approach to APF is demonstrated , have a better power quality insight using Matlab Simulink in order to develop new fuzzy logic controller based active power filte)
