Sorry, I found my mistake, MMSE-MRC is still better than MMSE . By the way, thank you so much for your post. It helps me a lot!

@minh: I have not compared MMSE-SRC vs MMSE. However, from my results comparing ZF-SIC vs ZF, I can see gains.

I have done simulation with MMSE-SIC but there is no diversity gain compared with MMSE equalizer. I have tried to find out the reason but I haven’t got it. Would you please give me an explain. Thank you in advance

@jhon: No, we form an estimate of one symbol. Then use that estimate to subtract the interference caused by that symbol to the other symbol.

what exactly is the meaning of successive interfernce cancellation?

when we subtract x2 from y1 to get x1,,, does this mean that we are cancelling noise common to both spatial stream?

thanks

@ w@p: Sorry, due to time constraints, may I refuse to debug the code
