Proakis Channels

Started by cpsh...@rediffmail.com November 2, 2007
Hi everybody...

I am trying to implement LMS equaliser for Proakis Channel B which has coefficients [0.407 0.815 0.407]. Now the problem is that I am not getting the perfect BER plot. If I remove the precursor and implement the channel e.g. [1 0.815 0.407] then I am getting good plot. But not with the exact proakis channel B.

I guess the problem is with tap settings. I have tried everything but I am still stuck at this problem.

Any help in this will be highly appreciated.

Thank You

Hi Chintan,

Is your LMS equalizer estimation assuming the presence of a pre-cursor??
You need to check the equations carefully.

Thanks and Regards,
