Thanks Mr. Leech, I have already seen this but when I use f = fopen(filename, 'rb'); It gives me an error saying “undefined variable or class”. When I write the filename as ‘filename’ which is under single quotes then it works but it takes some very weird data. It doesn’t load the same data

You can use file sink to store your peak value. It will continuously store the values until you close your program. Alternatively you can use head before file sink to limit your to program to specific time. Hope this helps! Priyanka > On 26. Apr 2018, at 01:42, ALEJANDRO RAMIRO MUNOZ <10031

Thank you JM and Sakthi, To Jean- I tried taking the absolute square of the collected complex signal and got the peaks in range of e-3(1/1000). Also to add to your notice the signal that I am collecting from the RTL-SDR dongle has amplitude in range of 0.04(peak to peak). Can we be sure of having

Hi, I am trying to receive a GPS signal and I am using RTL-SDR2832U, and an antenna with 40dB gain. According to my research, the signal coming from the satellite is at RF, and it gets downconverted in front-end to IF (Intermediate Frequency). Now, I need to remove that IF from the signal coming
