Step 1: use the LMS adaptive filter to eliminate the pulse interference, which could eliminate the correlation linear weight of the signal

Step 2: joint estimation of and

2.1 according to (11)–(13), we set ; the mth column can be obtained as

2.2 recast the mth column vector as the matrix

2.3 set

2.4

2.5 compute the SVD as

The best rank-one approximation of in the Fibonacci norm is obtained by

Where is the largest singular value, and and are the first columns of and , respectively

2.6 go to 2.4 until

Step 3: calculate the estimates of and
