这是用MATLAB来进行数字图象处理的程序。都是一些很常用的，很有价值。(This is carried out using MATLAB to process digital image processing. Are very common, very valuable.)

信号分析里常用，求局部极大极小值的位置！用积分平均的方法！(Commonly used in signal analysis, seeking the position of the local minimax value! Integral average method!)

svm的回归预测分析，包含源代码和数据，测试可用(svm regression analysis to predict, including source code and data, test available)

basic ofdm with interlever: The transmitter section converts digital data to be transmitted, into a mapping of subcarrier amplitude and phase. It then transforms this spectral representation of the data into the time domain using an Inverse Discrete Fourier Transform (IDFT). The Inverse Fast Fourier Transform (IFFT) performs the same operations as an IDFT, except that it is much more computational efficiency, and there is used in all practical systems. In order to transmit the OFDM signal the calculated time domain signal is then mixed up to the required frequency.
