Hello People.
I have implemented adaptive DFE using RLS algorithm given in Adaptive
Filter Theory by Simon Hykin.
Now what I did is that I implemented both the filter i.e. feedforward and
feedback combined.
w=zeros(31,1); where 1st 16 corrospond to FF and rest 15 to FB.
I_hat=w'*u; where u is column vector which contains vectors for FF and FB
filter. And my receiver works fine.
But when I try to implement both the filters separately, I am not getting
good results. i.e.
w=zeros(16,1); FF filter
d=zeros(15,1); FB filter
u= FF coulmn vector;
v= FB column vector;
I_hat=w'*u+d'*v;
So how do I update FF and FB filters separately?
Your guidance will be greatly appreciated.
Regards,
Chintan
