Hi,

I would like to ask the questions on MIMO :-D
We can double the data rate by using 2x2 MIMO (comparing with SISO).
So we will get N-time higher data rate if we use NxN MIMO.
Am I right ?

If I use the maximum likelihood detection
what about the BER of 2x2 and NxN ?
Is it the same ?

Thanks in advance
 

Hmm dear if you read the documentation of IEE and IEE for MIMO it give you clear idea about your situation. The BER is not like that when we are talking about wireless mediaum we have to consider number of issues including the localizaion and Fn factor. Furhtermore if we consider we are working in ideal environment reflection of frequency increase the BER and if you want less BER then you actually need to look how intelligent is the algo you are using for MIMO.
 
Thank you very much for your reply
In MIMO, I think that we face more interference from more antenna.
So I have asked for error rate of NxN compared with 1x1.
