摘　　要：提出了一种用于求解有限脉冲响应系统函数和脉冲响应的频域最小二乘算法（ＲＦＬＳ），可应用于非实时系统辨识．本算法具有精度高、运算量小、易于实现和能够达到很高阶数的特点．给出了算法的推导论证、定阶和实用问题的讨论以及计算实例．This paper delivers a frequency domain Least Squares method to compute thetransfunctions and impulse responses of FIR system which can be used in non- real-time systemidentification. This algorithm has the characteristics of high accuracy,low computationalquantity , easy to implement and having very high orders.It also gives the deduction of thealgorithm,discussion of order determination and application problems,appended by computersimulation results.
