I draw the BER vs SNR and i can't draw the data rate vs the SNR as i can't get a direct relation between the data rate ans the SNR in the equation?

anyhelp?
 

There is no direct relation between data rate and SNR. If you mean a channel capacity (maximum throughput rate), google the Shannon-Hartley theorem.
 

i want to plot equation 10 in this paper
and as u see it contains only the channel coefficients and the two sources powers

Why? That is equation 9 in your reference. Eq. 10 is only a substitution.
If you want to plot R vs SNR using MATLAB do the following:
SNR1=0:30; - this is for example
SNR2=0:30;
SNR1r=repmat(SNR1,length(SNR1),1); create a matrix from vector by repetition
SNR2r=repmat(SNR2',1,length(SNR2)); note that snr2 is transposed
Rate=0.5*log((1+SNR1r).*(1+SNR2r));
surf(Rate);

Is it a reply?
