MIMO system,how to know the each dimension of the CSI matrix which represent of single transmit−receive antenna pair

[linkzhao]

A commercial AP with two TX antennas ,NIC 5300 with two RX antennas , in other words I have a 22MIMO system.I have got the CSI matrix—2×2×30，but how to know the 11*30 CSI matrix represent of every single transmit−receive antenna pair?thanks! @dhalperi @dpward

Hi, First of all sorry I am asking irrelevant question in that thread.

But i want to know that the system you designed is fully MIMO-CSI ?

Is it possible that you can have 2 AP, two computers both transmit and receive at the same time, connected with each other, Getting CSI data as well. ?

you said you have a 22MIMO system,you have got the CSI matrix—2×2×30 , I have a 2×3 MIMO ,but I get csi includes 1×3×30 and 2×3×30, how to set to get only 2×3×30? @linkzhao

@lidongning ......

Are you successfully getting CSI data fro 2 x 3 MIMO?? You did it on Ubuntu??? Have you made one PC a hotspot??? Could you give an idea how you establish the connection between two Pc's ?

[lidongning]

I use AP as AP , I don't make hotspot , but now I want to set it ..... my NTX=2,NRX=3, I get 2330 and 1330 , but I want to only 2330 @danha170

hostapd mode , need 2 pcs? why hostapd connect router??? @danha170

[danha170]

@lidongning ..........But if I use router It will give me output,,But I want to try 2 AP.......

I have a question , How you set two transmitters??? PC with NIC 5300, you can use two or three antennas as a RX..but how to set 2 transmitters???

[lidongning]

sorry ,I only try a pc with 5300 and a AP @danha170

@lidongning ............. Ok i got your point.....I want to talk to you in detail, could u send me your contact....e-mail...........whats app..anything? If possible
