Top 11 C++ signal-processing Projects

gnss-sdr

13 1,472 9.2 C++

GNSS-SDR, an open-source software-defined GNSS receiver

Project mention: Just scrolled past a certain sarcastic Flatwittoid poast about not beïng able to see satellites in photographs. The whole frame of this represents *one single pixel of a high resolution* image, & the smiley represents a satellite. Details inside. | /r/flatearth | 2023-05-20

You realise you can write software yourself to interpret the signals from GPS satellites? Here's an open-source implementation.

Smoothed

1 71 0.0 C++

An Arduino library that allows smoothing of a sensor input using various methods. Uses a template class to ensure sensor readings in any numerical data type can be handled. This makes it both lightweight and flexible.

Project mention: New Arduino Smooth Library | /r/arduino | 2023-06-18

Please let me know if you run into any issues. I may re-write it to use a template as this existing array'ed Arduino Library does.
