Hi there,

I hope you will be doing fine. I am a GNSS researcher and a PhD candidate. I am working on GPS L1 C/A baseband signal and have recorded an IF signal for 120 seconds using RTL SDR. The signal file is saved in int8 and now I would like to convert it into int16 or int32.

Is it possible?

If yes how to do it? of course I wouldn't ask people to write a full algorithm for me but I just need a track. BTW I have also attached a signal file for those who want to give it a try.

Thank you so much in advance
