Please Help,Multipath Rayleigh Channel Equalizer

Hi Everbody,
I need your help I am not good at matlab/simulink,
My Problem is about Multipath Rayleigh Channel BER Calculation in Simulin/matlab.
BER Results are for the below cases;
Generating Data:Bernoulli Binary Generator
Modulation:QPSK Modulator
Channel:Rayleigh Fading and AWGN
Equalizer:LMS Based Equalizer
Demodulation:QPSK Demodulator
I am making BER/SER analysis by using modulate data after QPSK Modulator/Demodulator Block
The Results are according to SNR:
*(No Equalzer Block)There is no multipath Delay and Gain BER is acceptable 10e-4
*(No Equalzer Block)There is Multipath of 2 channel LOS+ 1 path BER is quite high %50(5 bit for 10 bit transmitted)(Delay[0 2e-8], gain[0 -9] for Rayleigh block)
*( Equalzer Block) There is no multipath Delay and Gain BER is quite high %50(5 bit for 10 bit transmitted)
What will I do? I am waitng the results of BER improved after equalizer in multipath effect rpt. Theory, Where am I wrong?
I hope is it possible to advise me about this topic, how can I take professional help?
I enclosed the simulink model.

Is there Nobody?
:

No Help

How nice
Is there nobody to help about this topic?

It's wrong if BER was 50%

I know man,
What is your advice

I have same problem in matlab code....BER is around 0.5...plz help

Hi realbaltalyus,

If you are using qammod and qamdemod for your simulations that might be problem, u need to write these function by yourself. i had the same pbs but used a modulation and demodulationfunction written by someone and my BER was zero, taht was when i was using AWGN tough, now am upgrding to multipath channel and i am thinking about how to write an equalization code for the multipath channel.
