How to implement interplex modulation in LabVIEW

 

Hello everyone,

 

I am using NI 5665 VSA with modulation toolkit to acquire and analyze RF data. At present I acquire IQ data at desire sampling rate. Now I want to analyze this data and this data is interplexed modulated signal. It has 2 modulation technique in it. One is BPSK and another is BOC. 

 

So can anyone suggest how to demodulate this interplexed signal in LabVIEW? As mentioned Modulation toolkit is already installed in system.

 

Another question is when I save the IQ data and try to demodulate using BPSK technique only then on constellation diagram I gor the points all over the circle and that might happen because of some carrier component still exist in IQ data.

 

Hence can anyone suggest how to remove that carrier component from I and Q data and How to shift the acquired data so that IQ demodulated data actually matches with ideal points of BPSK constellation diagram?

 

Any help is highly appreciated.

 

Thanking you in advance.
