次级通道建模是自适应主动噪声控制(AANC)系统的一个关键问题。
Secondary path modeling is a key issue of adaptive active noise control (AANC) system.
初级通道网和各种尺寸的次级通道网相联接，次级通道分送空气到各个房间的出风口。
This network of primary channels is connected to a series of secondary channels of various sizes which distribute air to the outlets located in the rooms.
在前馈有源噪声控制中，由于次级通道传递函数往往是非最小相位系统，直接使用传统的FXLMS算法时，导致系统的性能下降。
In the feedforward ANC, when the traditional FXLMS algorithm is applied directly, non-minimum phase(NMP) of the secondary-path transfer function will lead to the performance degradation.
