FIR
1、系统仅处于训练状态。训练序列为2cos(2π×f1×n/fs),
干扰为sin(2π×f2×n/fs);序列长度为100个样点。
其中n=0…99,f1=1kHz,f2=2kHz,fs=8kHz。
2、采用LMS算法,均衡器输入为训练序列加上干扰,均衡器阶数为21阶,步长因子β=0.01。
3、在Matlab中编写浮点LMS算法,绘制均衡器的输出波形,并与训练序列进行对比。
(1, the system only in the training status. The training sequence is 2cos (2πf1n/fs), interference sin (2πf2n/fs) sequence length of 100 samples. Where n = 0 ... 99, f1 = 1kHz, f2 = 2kHz, fs = 8kHz. 2, using LMS algorithm, the input to the equalizer training sequence plus interference equalizer order is 21 bands, step factor β = 0.01. 3, the preparation of the floating-point LMS algorithm in Matlab, draw the output waveform equalizer, and with the training sequence comparison.)

支持向量机
机器学习,支持向量机(SVM,还支持矢量网络)的监督学习模型相关的学习算法,分析数据,识别模式,用于分类和回归分析。给定一组训练实例,每个标记为属于两类,一种SVM训练算法构建了一个模型,分配新的实例为一类或其他,使其成为非概率二元线性分类。一个SVM模型是的例子如在空间中的点,映射使得的不同类别的例子是由一个明显的差距是尽可能宽划分的表示。新的例子,然后映射到同一个空间,并根据预测他们落在差距哪边就属于一个类别。
