Matlab-FFT-spectrum-analysis

对一种三相无源功率因数校正电路进行了参数的优化和仿真，仿真结果表明，运用Matlab中的SimPowerSystems模块对复杂的电路进行仿真分析和研究，不失为一种准确、直观有效的方法。 (Of a three-phase passive power factor correction circuit parameter optimization and simulation results show that the use of Matlab in SimPowerSystems module circuit simulation of complex analysis and research, after all, a precise, direct and effective way.)

这是一个MATLAB GUI源代码，实现黑白图像的滤波处理，MATLAB版本为7.6(this is a source code of matlab gui, which manage to filter the gray image.the version of matlab can not be older than v7.6)

gets the value of an environment variable.

matlab实现的一个扩展卡尔曼滤波程序，可以用于目标跟踪领域。(matlab implementation of a Kalman filtering process can be used for target tracking.)

need source code for matlab

Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high speed data transmission over multipath fading channels. High Peak-to-Average Power Ratio (PAPR), which leads to power inefficiency in the RF portion of the transmitter, is a major drawback of OFDM.

用于图像质量评价的ssim程序，用以对图像的质量进行客观评价，评价结果更接近主观感受(Ssim for image quality assessment procedures for an objective image quality evaluation, evaluation results are closer to the subjective feelings)

基于matlab的golden序列生成程序，可以参考使用(Based on the matlab golden series generate program, reference may be used)
