- 2 . the fast fixed - point algorithm has been studied . we firstly consider one unit algorithm , extracting one original signal every time under instantaneous mixtures model
- Finally we study a modified algorithm , which applies the fast fixed - point algorithm for complex signals to blind signals eparation in frequency domain . it ’ s a one - unit algorithm . to prevent converging to the same signal , the deflation algorithm is used to separate signals one by one
