Subject: destructive interference problem

I use 2 usrp N210 as transmitters and 1 usrp N210 as a receiver

My goal is constructing beamforming system

To do that I want to check destructive interference of the transmitted signals

So I constructed the blocks likewise the picture

Even though I changed the phase of one transmitted signal

But at the receiver nothing has changed

I couldn't check any interferences in the received signal

So are there any different ways to change the phase of signal?

I also used 'delay' block, but nothing has changed
