GNU Radio module for OFDM spectrum painting
conda install ryanvolz::gnuradio-paint
The goal of this project is to build a software-defined OFDM transmitter that "paints" monochrome images into the waterfall of a receiver. It is based on https://github.com/polygon/spectrum_painter. After installation, a GNU Radio block called "Spectrum Painter" will be available in the "Paint" category. The block converts a byte stream of image data into a 4K IFFT OFDM IQ sequence for transmission.
