构造一组输入为白噪声加三个频率非常接近的正弦波，其信噪比为10dB，观测长度为256。试分别用普通AR谱估计和采用功率噪声抵消算法的AR谱估计估计这组信号的频率，并比较结果。(constructed a group of white noise input plus three very close to the frequency sine wave, the signal-to-noise ratio of 10dB. Observing length of 256. Were used to test the general AR spectral estimation using power and noise canceling algorithm for the estimation of AR spectrum estimation of this group of signal frequency, and the results of the comparison.)

这是我们计算机控制的一个上机题,希望大家的学习有所帮助(This is a computer-controlled machine on that, I wish you all a learning help)

说明：  两个adaboost算法，代码很短，都有中文注释，第二个代码是第一个的改进。(Two algorithms about adaboost ,the code is very brief,including the Chinese comments. The second one improver better than the first one.)
