The convergence gain of least-squares algorithms over steepest descent algorithms for multichannel ANC systems has already been documented [1], so results about numerical stability of the recursive-least-squares algorithms will mostly be discussed here. Table1 compares the numerical stability of the different recursive least-squares algorithms. If the algorithm is... ..."

De ne e(j) m (n) = m X p=1 quot;(j) p (n ? m + p): (28) Then, we can de ne a set of IJL auxiliary coe cients b w(i;j) l (n) whose updates are given by b w(i;j) l (n + 1) = b w(i;j) l (n) ? e(j) M (n)x(i)(n ?

Table1 lists the operations of this implementation,... In PAGE 13: ....2.2 An Alternate Implementation Although useful, the delay-compensation method in (37), (39), and (41) can be prohibitive to implement when the number of channels is large, as its complexity grows as O(IJKM). We now consider an alternate implementation that uses many of the existing quantities within the e cient multichannel ltered{X LMS algorithm in Table1 while avoiding the formation of the ltered input signal values. For this derivation, consider the de nition of (j;k) m (n) in (40).... In PAGE 14: ... Table 5 lists the operations for this alternative form of the LMS algorithm for multichannel active noise control. This algorithm requires JKM + J(M + 1)(M ? 1) more MACs per iteration than does the ltered{X LMS algorithm in Table1 . If M ? 1 M lt; (4I + 1)K; (47) then this implementation is more computationally-e cient than that in (37), (39), and (41).... In PAGE 16: ... Figure 3 shows the unattenuated air compressor noise signal, in which the bursty nature of the compressor noise is clearly evident, along with the average error power envelopes of the original ltered{X LMS and LMS algorithms applied to this data, in which the step sizes for each algorithm were chosen as = 0:1 and = 0:2, respectively. Shown for comparison in Figure 4 are the average error power envelopes of the adjoint LMS/CPFE algorithm, the fast ltered{X LMS algorithm in Table1 , and the new multichannel LMS algorithm in Table 5, in which the step sizes for each algorithm were chosen as = 0:05, = 0:1, and = 0:2, respectively. As can be seen, the fast multichannel ltered{X LMS algorithm outperforms the adjoint LMS/CPFE algorithm in its convergence rate, and the multichannel LMS algorithm performs the best of the three due to the lack of coe cient delay within the parameter updates....
