可以实现QPSK解调的matlab代码，希望对大家有所帮助(realize QPSK mode)

说明：  用于模拟时变非平稳的ARMA过程，根据Doppler频移和时变参数计算ARMA过程的系数，可以用来模拟非平稳的多径衰落信道(used to simulate nonstationary time-varying ARMA process, according to Doppler frequency shift and the time-varying parameters ARMA process coefficient, can be used to simulate the non-stationary over Fading Channels)

该方法为遗传算法，能解决一系列不定问题，所以效果很好。(The method of genetic algorithm, can solve a series of indefinite problems, so very good.)

希尔伯特变换理论及matlab程序( Hibert for matlab )

说明：  一个用MATLAB实现的单位转换程序，包括质量单位转换和长度单位转换。(MATLAB realization of a unit with the conversion process, including quality and length of unit conversion unit conversion.)

parzen窗估计及matlab源程序(parzen windows estimates and matlab source)

粒子群算法的matlab实现，用于函数优化(it is a PSO program which is made by matlab)

matlab工具箱应用简介，希望能有所帮助 (matlab toolbox application profile, hoping to be helpful)

contrast adjusment Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view. Because the human visual system is more sensitive to contrast than absolute luminance, we can perceive the world similarly regardless of the huge changes in illumination over the day or place to place. The maximum contrast of an image is the contrast ratio or dynamic range
