Hi,

I've got one question regarding the possibilities when modificating the
firmware: Is it possible to manipulate the modulation via firmware eg
adjusting the QPSK when sending a symbol? Like sliding single symbols in
the Q/I plane by a fixed value apart from the intended location? The
following picture illustrates the modification:

If this is not feasable: Is there any wireless lan chip known having
open source firmware/software which is capable of doing so? I'm not
talking about SDR but *normal* wlan hw.

Sincerely,
mike
