Hi,

I have some doubts on the matlab code of WCDMA ahmed has uploaded here...

1. what is the significance of Sur_Len=40; and Push = 3;
2. In the following section
if(kpw>0)
Sig_Rec_Tmp=Sig_Rec*Gold_Buf(end)';
Sig_Buf(mod(kpw-1,Plt_Num*SF)+1,:)=Sig_Rec_Tmp;
Sig_Est=Sig_Est+Sig_Rec_Tmp; %Estimation
end
Why we does not multiply the whole window length of gold buffer with the received buffer and sum and again shift the window.
Is it not a sliding correlator.
3. How can we get a channel impulse response without actually despreding the pilot bits??

It will be a great help if anybody could clear these doubts.

thanks,
Shameem
 

Thanks for the code too. I'm still looking into it. The pilot channel or we should call it CPICH for wcdma should be despreaded to estimate channel.
Overall the code is of good quality. I know someone in ecvale is asking to buy sth like this. Ahmedseu, you may want to double check it.
 

Hi,

Could anybody please upload a document for this matlab implementation.

Thanks,
Shameem
