Hello !
I have two question !
Ordinal of Antenna between 2 node have affect BER of mimo ?
case1:
antA antB
antB antA
case2:
antA antA
antB antB
How to change ordinal of antenna in WARPlab ?
Thanks !

The WARP v3 board has two RF interfaces labeled RF A and RF B. You can assign whatever Tx/Rx signals you want to each RF interface. For example, in the WARPLab MIMO OFDM Example constructs two complex waveforms tx_vec_air_A and tx_vec_air_B, then assigns these to RF interfaces A and B. You can swap which waveform is assigned to which antenna by changing these variables.

Thanks you !
I have more question.
When Signal DONE (Reset RX) in ofdm_txrx_supermimo_coded/OFDM Rx MIMO/Equalizer & Packetizer/Packet_Constructor/Data Buffer == 1 ?

I'm sorry, I don't understand what you're asking.

Sorry !
When Signal DONE = 1 in Rx of ofdm_txrx_supermimo_coded ?
In option of modulaton have BPSK,QPSK,16QAM,64QAM ! but when i selection 64 QAM in mimo reference . Rx don't detection true data.
When i connect Tx vs Rx
Thanks

The DONE signal is asserted by the Viterbi decoder block when it has decoded the last byte of the packet payload. You should observe a DONE signal for any modulation/coding rate if the Rx PHY was able to decode the packet header and attempted to decode the packet payload.
