DCT去噪，利用MATLAB实现DCT去噪，从而提高图片质量。(DCT de-noising, de-noising using MATLAB realize DCT, thereby improving image quality.)

The Fourier transform, named for Joseph Fourier, is an integral transform that operates on the mathematical representation of a function in time and produces a function in frequency. The term Fourier transform customarily refers to both the transform operation and to the function it produces.

三相并网系统，包括锁相环，坐标变换，解耦控制等算法，通过验证(Three-phase grid-connected systems, including phase-locked loop, coordinate transformation, decoupling control algorithm, validated)

The NAVSTAR GPS (NAVigation Satelllite Timing And Ranging Global Positioning System) is an all-weather, space-based navigation system developed by the U.S. Department of Defense to determine ones position, velocity, and time accurately in a common reference system on the Earth. The present constellation consists of nominally 24 satellites and provides global coverage with four to eight satellites simultaneously observed above 15 ? elevation.

形成一个余弦调制波形，用于调制波形，具有非常重要的意义(Form a cosine wave modulation for modulation waveform, has great significance)
