Creating an I/Q waveform file from ADS-B dataset.

Hello,

I am trying to create I/Q waveform file using ADS-B 1090 dataset that I can feed in to vector signal generator. Sample data is

8800004699080100200401A5E1EE

88000040480B01FBC837271C5957

88000041480B01FC1A3758EA63E1

8800004199080100200401221309

sample rate is 50e6

Any help would be greatly appreciated.

Thanks in advance.

Hi @Ketan Bharucha,

To process and extract message from ADS-B data you can refer to the following documentation link from Communications Toolbox:

https://www.mathworks.com/help/comm/ug/airplane-tracking-using-ads-b-signals.html#d126e18935

IQ waveform consists of two sinusoid signals with real and imaginary values, where the extracted message from ADS-B needs to be embedded. You may refer to the following documentation link for a relevant example:
