这个程序主要是实现QAM的调制和解调的过程。(This procedure is mainly the implementation QAM modulation and demodulation process.)

Wavelet Transforms and JPEG2000

实现频谱分析。能显示信号与频谱图。主要是对正弦信号和三角波进行一维FFT变换，得到频谱图。(To achieve spectral analysis. Shows the signal with the frequency spectrum. Sinusoidal signal and triangular wave one-dimensional FFT algorithm to obtain the frequency spectrum.)

求一元二次方程ax2 +bx+c=0的根(Find a quadratic equation ax2+ bx+ c = 0 root)

频域内低通滤波实现图像平滑，程序原代码来自书籍，《计算机图像处理与识别技术》，作者王耀南等(frequency low pass filter)

PAPR Reduction based on a Modified PTS with Interleaving and Pulse Shaping method for STBC MIMO-OFDM System. It is with GUI. Using GUI we can see comparison with number of sub carrier, sub-block and over sampling factor as well BER plot comparison of normal and with PTS technique. You need to run MIMO_OFDM_with_PTS.m Note: Do not delete or rename amy file and place all the files in one single folder because some are functions which are called in GUI code.

预测数据，数据分析,进行经济数据的多年预测，用途广泛(Forecast data, data analysis, multi-year forecast of economic data, widely used)

It contain pdf of digital image processing which describes the some image processing concepts like image acqusition,image pre-processing etc.

说明：  分叉图是混沌系统的一个重要参数，现以洛伦兹系统为例，给出分叉图的matlab程序(Bifurcation diagram is an important parameter of chaotic systems, Lorenz system, taking as an example of bifurcation diagram matlab program)

BA_GMRES 内迭代预处理的GMRES(Inner-iteration for GMRES)
