How can i implement maximum ratio combining method(MRC)?

Hello i want to implement maximum ratio combining . I have 2 antennas(recievers) and one transmitter .So far my code is like this :

for i=1:2
    SNRdb=20;
    y(i,:)=h(i,:).*s;
    sw2=1/(10^(SNRdb/10));
    noise(i,:)=sqrt(sw2/2).*(randn(1,N)+1i*randn(1,N)); %create noise
    r(i,:)=y(i,:)+noise(i,:);
end

where s is a 4-QAM modulation and h is a complex channel h~CN(0,1). All matrices are 2x500 . I have to implement maximum ratio combining method .What am i supposed to do? is this right ?

where Y suppose we have R in my code.

Any help would be valuable!

Please review the shipping example: Introduction to MIMO systems, that offers the maximal ratio combining as one of the MIMO schemes.
