Hi guys, I have succeeded to plot out my packet data after modulation -I used sdr radio usb in order to succeed to get the data of my transmitted packet, the transmission done from chip cc1350 and I've plot out by matlab , the data of the packet ..
-- attaching down my matlab photos-
what's confusing me, Im not succeeding to analyze and know why I have clipping in my packet data - the clipping showing in matlab- .. it shouldn't be but apparently there's something going on and Im not succeeding to know why this clipping happening, could anyone help me please?/?

the first one is FFT of my one packet data, the second one used plot for my data one packet that has been transmitted wihtout FFT feature
