Evolutions of PI ( Ni ) for six different runs of the ANPCA algorithm using 350 ms ISl. The performance of the ANPCA algorithm in (31) was evaluated using (35), where W(0) = I. A single block of N= 7000 samples has been used to compute all coefficient updates for six run, where $\widehat{x}\left(k+Ni\right)=\widehat{x}\left(k\right)$ for all integer values i ≥ 0 and i ≤ k ≤ N-1.
