lms algorithme

good morning

am working in my final project
& it is about lms_mimo_mccdma

i have probleme in matlab programme

& its about the µ of LMS algorithme

am working now with µ=0.12
& the results r good

but in theory
this is a big number & it must be about 0.05 or less

can any one tell me if am good or no & why
 

Re: lms algorithme

hi..

the learning rate of lms algorithm is lower bounded by 0 and upper bounded \[\frac{1}{\lambda_{max}}\] where \[\lambda_{max}\] is the max eigen value of the input or u can just take the 1/(signal power) as the upper bound.

better reference is Simon Hykins - adaptive fiter theory.

hope this helps..

hi..

thnx a lot rakesh

do you have information about smart adaptative antenna?

& do you know how can we add the canal effect & the additif wait gaussien noise ?? in matlab of course
