GNURadio with VLC - IM/DD Modulation Techniques

Hi Everyone,

I’m writing to ask if anyone is familiar with work being done using the
GNURadio project for communication outside the RF spectrum. I’ve been
working with the software and USRP for about a month and I’m using a
Visual Light Communication (VLC) front end for the physical link. I’ve
gotten a 1Mb/s link using the benchmark BPSK modulation, but before I
attempt to create any techniques I wanted to see if anyone knows of any
available examples for IM/DD techniques such as Pulse Position
Modulation or Pulse Amplitude Modulation.

Thanks in advance,
