变步长的最小二乘递推算法

The New Method of Recursive Least Squares of Changed-step

针对固定步长的最小二乘递推算法在信号辨识中采集数据量大、辨识速度较慢的缺点,提出了变步长的最小二乘递推算法,在保证同等辨识精度的条件下, 采集的数据明显减少,大大提高了辨识速度。

This article aims at the problem that RLS of the fixed step demand collecting the large quantity data and identifiably speed slow in the signal identification, bring upping RLS of changing step makes, under guarantee the condition that equal identification accuracy, Obvious decrease of data of collecting and Consumedly increased to the iden-tifiably speed, and obtain the good result.
