Description: I provided him a little example of a single channel feed-forward active noise control system based on the FxLMS.
To reduce noise, we generate another 'noise' yw(k) using the controller C(z). We hope that it destructively interferes x(k). It means that the controller has to be a model of the propagation medium P(z). Least mean square algorithm is applied to adjust the controller coefficient/weight.
However, there is also fluid medium S(z) that stay between the actuator and sensor. We called it the secondary propagation path. So, to make the solusion right, we need to compensate the adjustment process using Sh(z), which is an estimate of S(z).
