I am receiving 16-bit data from USRP (data is in the range of -32768 to 32767) in Windows. Now I want to apply some demodulation algorithms to these samples but I am a bit confused. According to the following thread, each data sample that is coming from USRP is a complex baseband value. However, a complex baseband value should be of 32 bit (and not 16-bit) as it comprises of 16-bit I and Q each. http://www.ruby-forum.com/topic/182559
So the data samples that I am getting are in the form of I0,Q0,I0,Q0.... or a sum: (I + Q)? If these are in the form of I0,Q0 ... then how do we keep a track that which one is an I and which one is a Q?
