@Amit Kumar: I do not have a code explicitly for MIMO multiuser cases. However, just to add that MIMO VBLAST case can be equivalently thought of as multi-user scenario.

Dear sir,
I want to write a program for BER performance for MIMO in Rayleigh channel in multiuser environment.
If there is any code for multiuser MIMO system pleas mail me.
thanking you.

@John: Not sure I understand your query. Ordering is based on the SNR of the received symbol

Hello! Kirishna how are u ! I confused about the “MIMO with ZF SIC and optimal ordering “ step-(f) Take the symbol having higher power, subtract from the received symbol, whereas according to the paper “Detection algorithm and initial laboratory results using V-BLAST space-time communication architecture”–formula 7c , it seems that the optimal order should be selected from the minmum, could you help me to solve the problem!thank you

@Gabriel: The variable hCof corresponds to the co-factor matrix (used when computing the inverse). Then based on the channel power H, we sort the cofactor matrix accordingly.

The sorting of the equalization matrix based on the channel power is not clear for me. What is hCof? Can you explain it a little bit more?
