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
