the problem of the receive data on the zc706

I am using the ad9361 on the zc706 to transmit data ,here  I put the data modulated by QPSK into the ad9361 ,this is the data I send:

45964-770f2003a4a150b8834adbde3bb76ef0.jpg

my question is why I  always get different waves from  the ad9361 at the receive point.like:

43207-5ea544c83eba692b089aed4194589658.jpg

this is the one case,another is showed below:

41960-902a695f71db34f00586f14ca76ca7c0.jpg

we can see the blue wave in the second figure is the converse of third one and there are other cases like this.

my sending data is the same each time .so any ideas?
