active noise control using kalman filter

hi everyone, I'm doing a project in active noise control using kalman filter.

I'm taking simulink-models as reference, which are demos> blocksets> signal processing> adaptive processing> acoustic noise cancellation (ANC), tracking filter (kalman). I need some guidance about how to implement the ANC using kalman filter.

I tried a few configurations and replaced the normalized LMS filter with kalman in ANC. I connected "pilot's mic" to "In" and "ext. mic" to desired input d(n) (positive input in summer at Kalman's "out") and kept rest of the ANC circuit same. Now, when I run it, it gives an error
"Check signal attributes. Input must be sample-based." why is it giving this error?

Please give some suggestions on how to implement it.
Can you mail me the details of the project you done on the kalman filter.
my mail address is <snip>
