Simulink LMS Equalizer design

Hi All,

I have a project for QPSK Modulation-Demodulation.

I set the below block in simulink

Bernoulli Data Source==>QPSK Modulator==>Multipath Rayleigh Channel(Also with delay vector and ga,n)==>AWGN Channel==>LMS Equalizer(Decision Feedback Equalizer)==>QPSK Demodulator ==> BER Calculator

BER is too high the problem is when I added LMS DFE in the model and the BER is about 0.5,

The SNR(increasing) does not solve the problem.

How can I solve this?

I look for some help
