Question about USRP Synchronization when using 1X 2 MIMO

[ahmetemir]

Hello,

I wonder topic about 1 X 2 MIMO ( One transmitter Two Receiver USRP System ) .I have input bit sequence like '10101010...' on transmitter part. So '1' and '0' bits  are lined up in  order. 0 comes after 1 , 0 comes after 1 .I want to send this bit sequence  from transmitter USRP to channel. On receiver part;  how could I set time  and set up triggers of receiver USRPs that  one USRP will fetch only 1 bits from these squence, another USRP will fetch only 0 bits from thise squence. How Can I synchronize this 1X2 MIMO system like that ? Could you give me advices?  

Best Regards.

Hi ahmetemir,

What specific hardware and software are you using for this application? 

[ahmetemir]

Transmitter will be 2943R , one of the  reciever will be 2921 other  of the  receiver will be 2943R.  Should I use only Optoclok for synchronization?  I couldn't write software specific , I couldn't know how I'm able to to implement this system. Software editor is NI Labview 2014. Is there any example program similar to this problem?? Could you give me advices please??

Hi ahmetemir,

I think this example will provide a framework for what you are trying to do: https://decibel.ni.com/content/docs/DOC-23677.

Thanks for your help, I will review exapmle

anyone share with me a VI with Implementing 2x1 MISO system with LabVIEW and NI USRP 2921 using Alamouti code?? I need problem with the estimation channel in the receptor, i used the alamouti code with 2 antennas trnasmitter and one antenna receiver.
