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.
