对非线性方程，要求一定的精度，用matlab求解。(Nonlinear equations require a certain precision, using matlab to solve.)

数字图象处理系统，使用MATLAB的GUI模块，可实现图象的直方图均衡、灰度化、二值化、缩放、边缘检测、增加噪声、图像变换、去噪等功能。使用时请将fig文件和m文件和图像放在一个文件夹内(photo process system,use matlab)

正交频分复用基于IEEE802.11a的PTA跟踪法，同学自己编的，较复杂，运用了锁相环(Orthogonal frequency division multiplexing IEEE802.11a-based tracking method of the PTA, the students made their own, and more complex, using a phase-locked loop)

指数平滑法，它提供的预测值是前一期预测值加上前期预测值中产生的误差的修正值。(Exponential smoothing method )

最近用Mega128写了一个128点FFT程序，浮点运算，加汉宁窗。由于窗函数和旋转因子通过查表得到，所以速度还可以，程序中给的初值是通过高速AD采集的20KHz正弦信号。计算结果与Matlab的FFT函数得到的结果相同。 (Mega128 recently wrote a 128-point FFT procedures, floating-point operations, Hanning window. Since the window function and the twiddle factor look-up table has been adopted, so the speed can also be, the initial value to the process through high-speed AD collected 20KHz sinusoidal signal. The calculation results with the Matlab)
