Abstract(in English)	This paper investigates the performance and the effect of a multi-point noise controller combined by individual single-point noise controllers. The convergence and residual error of the multi-point canceller are mainly investigated based on the cross-connection matrix C_(z) which denotes the transfer functions from the output of each adaptive filter to every noise cancelling point. The relation between the optimum solution of adaptive filters and cross-connection matrix C_(z) is deduced. The influence of non-diagonal components c_(z) (i≠k) on the convergence and the residual error is investigated through computer simulation. The following simulation results are achieved. The optimum solution can be obtained as long as C_(z) is not singular. In the case of that c_(z)(i≠k) is in proportion to c_(z) adaptive filter converges slowly when r increases. But the residual errors are almost the same. In the case of that c_(z) (i≠k) is different from c_(z), more number of taps is needed when c_(z)(i≠k) is far away from c_(z).
