2)add the rls filter to the file from library.
3)input are given to the input port.
4)add the noise signal to the desired port.
on the other hand you can find
5)error output at error port by connecting display block.
6)filter output at output port by connecting display block.
7)weight of the filter at wts port by connecting display block.
if you want the signal means replace display block with scope thats it
Hope it may be Helpful...
