lattice filters

In "Adaptive Filter Theory," 4th Ed., pp. 181-184, a description is given of using a lattice filter to solve the joint-estimation problem. In Fig. 3.13 (p.183), a diagram of the filter is given, where basically we have the backward prediction errors from the lattice filter used as input for a transversal filter. I'd like to use this filter. My question is: does adaptfilt.lsl, for example, have a similar structure? For example, does the example given in help for this function

ha = adaptfilt.lsl(32,lam,del); [y,e] = filter(ha,x,d);

perform this function? (x is the input signal and d is the desired signal.)

Thanks in advance,

Brad

Hi, Yes, it does. As you suggest, x is the input signal and d is the desired signal.
