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)

Real-Coded-Genetic-Algorithm-for-Robust
Power system stabilizers (PSS) are now routinely used
in the industry to damp out power system oscillations. In this paper,
real-coded genetic algorithm (RCGA) optimization technique is
applied to design robust power system stabilizer for both singlemachine
infinite-bus (SMIB) and multi-machine power system. The
design problem of the proposed controller is formulated as an
optimization problem and RCGA is employed to search for optimal
controller parameters. By minimizing the time-domain based
objective function, in which the deviation in the oscillatory rotor
speed of the generator is involved stability performance of the
system is improved. The non-linear simulation results are presented
under wide range of operating conditions disturbances at different
locations as well as for various fault clearing sequences to show the
effectiveness and robustness of the proposed controller and their
ability to provide efficient damping of low frequency oscillations.
