802.11p GNURadio
Abstract—In this work we present an implementation of a
fully functional IEEE 802.11p transmitter in software-defined
radio. We describe the rapid-prototyping methodology that was
used to implement the frame-encoder within the open-source
GNU Software Radio (GNURadio) platform [1]. The encoder
generates OFDM frames in digital complex base-band representation
and uses the USRP2 [2] as digital-to-analog front-end for
up-conversion and final transmission. Since the actual encoding
process involves a large number of complex steps we split
the development approach into three sequential stages. First, a
reference-encoder in a high-level language (MATLAB) is derived
from the IEEE standard documents. Second, the individual
blocks of the MATLAB encoding chain are progressively ported
to GNURadio, cross-checking with the reference after each step.
Finally, standard compliance is verified by conducting comparative
over-the-air measurements with an early prototype of a
commercial 11p transceiver. Initial measurement results indicate
that the fidelity of the resulting GNURadio implementation is
on par with non-software-defined radio industry solutions and
capable of generating truly standard-compliant OFDM frames.
The encoder presented here has been released under GPLv3 and
is also capable of encoding frames according to the 11a and
11g amendments, thus making it a valuable building block for
upcoming software-defined radio projects.
