matlab语言实现的脊波变换源程序，图像多尺度分析的经典算法。(matlab language of the ridge wave transform source code, images, multi-scale analysis of the classical algorithm.)

说明：  完整详细的介绍OFDM系统源码，保证代码能运行。(OFDM system described in detail the full source code, to ensure that the code can run.)

Tutorial Two (You should run it in the Command Window)

The code description is inside the .RAR. Matlab code to anwser my university homework.

OFDM系统的简单代码，便于初学者理解，设置了N=128个信道，传送1,0的随机数，并加入fading和AWGN noise(OFDM system simple codes, for beginners to be understood that the channel 128 is provided, fading and AWGN noise added)

对数据进行EMD分析时，如果数据不是纯的白噪声,则分析过程中一些尺度将会丢失,出现模态混叠现象。EEMD通过附加均匀分布 在整个时频空间的白噪声，可有效抑制这种现象的发生。(EEMD is insufficient for the EMD method, we propose a noise-assisted data analysis methods. EEMD decomposition principle is: when the additional white noise uniformly distributed throughout the time-frequency space, the time-frequency space is carved up by the filter component of the composition at different scales.-)

eye pattern, also known as an eye diagram, is an oscilloscope display in which a digital data signal from a receiver is repetitively sampled and applied to the vertical input, while the data rate is used to trigger the horizontal sweep. It is so called because, for several types of coding, the pattern looks like a series of eyes between a pair of rails. It is an experimental tool for the evaluation of the combined effects of channel noise and intersymbol interference on the performance of a baseband pulse-transmission system. It is the synchronised superposition of all possible realisations of the signal of interest viewed within a particular signalling interval.

Using Matlab to solve some engineering problems

说明：  正弦发生器，可以根据自己的需要改变参数，实现仿真(an example solution of sine wave generator)
