That was pretty much what I wanted to say.
"State of the art in SDR" is very *very* ambiguous; it could refer
to
* SDR as a tool to make transceiver or measurement systems, and in
that both the fact that existing non-SDR systems are now SDR, or
that new systems are possible with SDR,
* SDR hardware, and in that the analog part, the ADC/DAC part, the
digital signal processing hardware,
* SDR software, and in that the actual systems, the actual
algorithms, or the architecture.
"GNU Radio" only describes the very last part, i.e. an architecture
to do the software side of signal processing in SDR. It doesn't say
what algorithms your specific system uses, or what bigger thing your
system is, or whether your system is just a simulation, a
communication transceiver, a radar device, a quantum measurement
tool, a guitar effect, something to automatically spray your cat
with water...
So, "state of the art": WHAT art specifically? "SDR" is a HUGE
topic, and GNU Radio only covers a very specific aspect of that. I
think you really should try to understand, in more detail, what
components make up an SDR system (which is something typically
taught in universities), and to which components of that model GNU
Radio maps. Then you can actually ask very valid question that will
be easier to answer, and much more interesting!

Also, the question is somewhat bifurcated. There are two
aspects:
(a) Which parameters in the hardware end of things have
advanced, and at what rate, and what is considered "state of the
art". This gets broken down into a few sub-categories:
o ADC/DAC speeds
o FPGA gate-counts and speed
o frequency-range of the analog front-ends, and analog
performance (noise figure, OIP3, etc)
(b) Advances in GPP hardware that support high-speed DSP on a
regular computer, and somewhat orthogonal to that, what "kewl
new stuff" has been implemented, and at what rate does that
happen, and where can we expect the "art" to evolve.

Hi,
Thank you so much for your answers.
Maybe i did not express myself correctly in my
original mail.
I am taking a course on SDRs at my university, and
an assignment is to do some research about SDRs,
especially on the state of the art of SDR, by this i
mean, the most cutting edge technology that is
available nowadays on the field. I have not been able
to found information about this on the internet, just
different frameworks used for developing SDRs.
However, i have to justify somehow, that gnu radio is
useful for serious academical research and not a
program for modest projects (not that i think that is
this way but i have to justify it somehow). For
example, quote some important projects developed in
gnuradio, or important companies working with gnu
radio, etc.
Are there any books or papers that investigate this
matter, and explain thoroughly what is the most
advanced technology to perform virtualization of
signal processing and why gnu radio is a good choice
for this task?
Thanks in advance.
