[Discuss-gnuradio] Highest Datarates with GNURadio

[mrahaim]

Hi All,

I started working with GNURadio a few months ago as a platform for use 
with a Visual Light Communication front end.  I've had some good 
success with the basic benchmark testing and implementation of a few 
basic tests with GRC, but I'm curious as to what datarates have been 
achieved within the GNURadio community.

As of now, I've been able to reach rates of 4Mb/s with GMSK and BPSK 
modulation and I'm pretty sure I've reached the limits of what my PC's 
can handle in real time (I seem to be getting errors occurring mostly 
from system overruns).  I haven't gone into testing with the OFDM 
blocks or higher order modulation schemes, but I wanted to see what 
type of rates I should expect.

I'm using the system mostly as a testbed for the time being, so my 
thought is to do the signal processing offline (to / from a file) and 
have the transmission simply sending and receiving from a file.  If 
anyone has suggestions or examples of how to do this it would be 
greatly appreciated.


Thanks in advance for any thoughts,
