用Welch法进行功率谱估计
- 考虑L的三个不同值:L=256(3个数据段),L=128(7个数据段)和L=64(15个数据段)。各自的谱估计图如上图所示。可以明显的看到,加窗明显的减小了频谱上的假谱峰,但也更加进一步平滑了谱峰。所以,对于L=64的情况,在ω=0.8π的谱线可以很确定的辨认,但是那两个靠近的谱峰不容易区分。对于L=128的情况,这种情况提供了在分离和检测间最好的均衡。当然,对于在L=256时的情况,效果是更好的,能够从谱估计图上明显的分辨出三条谱线的存在以及它们幅度关系的强弱。 除了Welch法外,还可以采用

functionz
- 在三次样条中,要寻找三次多项式,以逼近每对数据点间的曲线。在样条术语中,这些数据点称之为断点。因为,两点只能决定一条直线,而在两点间的曲线可用无限多的三次多项式近似。因此,为使结果具有唯一性。在三次样条中,增加了三次多项式的约束条件。通过限定每个三次多项式的一阶和二阶导数,使其在断点处相等,就可以较好地确定所有内部三次多项式。此外,近似多项式通过这些断点的斜率和曲率是连续的。然而,第一个和最后一个三次多项式在第一个和最后一个断点以外,没有伴随多项式。因此必须通过其它方法确定其余的约束。最常
