Hi Martin, Thank you again for getting back to me. Let me elaborate on the process that I am doing, and hopefully what I need will be clarified.
I have two USRPs connected via MIMO cable that are transmitting a sin wave and one USRP receiving that sin wave. I am trying to implement a system in which I determine the power of the received signal, feed it back to the transmitters, adjust weights that I'm multiplying the transmitted signals by (according to some algorithm), and then send again to the receiver, and this goes on for a certain number of iterations. The problem I am having is that I have no idea how to make sure that the received signal is the one that I am transmitting with my correct weights. In other words, I want to turn that receiver on only for it to receive my signal that I transmitted, then turn it off again as I adjust the weights, and then transmit again, and have it receive again. So, it's basically a full feedback loop that is sequential: transmit new signal, receive that signal, send back some information about that, transmit new signal, receive that signal, etc. I still feel like I'm not able to describe this articulately, so please keep me posted. I am a bit unclear on how the rx_time could work in this above scenario. Thank you so much again! -- Pavan
