重要是实现通过瑞利信道的QPSK的仿真，同时给出了其误码率的仿真(Important thing is to achieve through the Rayleigh channel QPSK simulation, while its error rate is given simulation)

电池全寿命加速老化试验的采集数据。在不同温度下的充电和放电下完成。数据格式为matlab的mat，文件里面有详细的实验数据说明，希望对研究电池寿命预测和诊断的同志有帮助。(Battery life-accelerated aging test data collection. At different temperatures to complete the charging and discharging. The data format is the matlab mat, which has detailed documentation of the experimental data shows that the hope of battery life prediction and diagnosis to help comrades.)

基于matlab，利用香浓能量对心音信号进行包络提取(Based on matlab, using Shannon energy of the heart sound signal envelope extraction)

部分全国大学生数学建模竞赛题，及报告，算法很好(The title and the report of part of the National Undergraduate Mathematical Contest in Modeling)

实现图像的DCT高通、低通滤波器并与傅里叶变换做比较.有图可见，经DCT低通滤波后，图像变得很模糊。因为DCT是FFT取其实部，能量减少，因此图像变得很模糊，没有经FFT滤波后的效果好。 经DCT高通滤波后的图像： 经DCT高通滤波后，图像的低频部分被滤除掉，图像变黑，只有边缘的痕迹可见。 (The DCT of image high-pass, low pass filter and compared with the Fourier transform.)
