URSP is necessary for develop a block and test it?

Hi. First of all I apologize for my bad english. I am a student in
Computer Engeneering at University of ROMA TRE, Rome Italy. I’m taking a
course of SDR and for my project I would wrote a block for SDR Radio for
implement MIMO wireless feature. Now I don’t understand if I can do this
without a motherboard USRP but only with a wireless MIMO card.
