Hello everyone,
I was trying to understand the various parameters used in adaptfilt.lms() function
The general form is:
H = adaptfilt.lms(L,STEPSIZE,LEAKAGE,COEFFS,STATES)
Here, L : lemgth of the adaptive filter
STEPSIZE : μ
LEAKAGE : α
COEFFS : , i.e., Initial coefficient vector of the adaptive filter
where,
But, i was not able to figure out what is STATES ?
In Matlab, it is given that STATES is a vector of initial filter states. It must be a length L-1 vector.
STATES defaults to a length L-1 vector of all zeros.
But I don't understand how it is related to LMS Algorithm described by the above equations
so, please anyone explain it
