Abstract:
|
This paper describes some of the outcome of the FP7 project
PHYDYAS, whose main objective was to propose a new physical layer that will
enable introduction of cognitive radios and dynamic access spectrum
management. During the project both a software simulator and a demonstrator
have been developed. A description of the demonstrator and some simulation
results that show the differences in spectral efficiency and the sensititvity to
synchronisation errors between OFDM and FBMC are given.
The simulator, which is written in Matlab, was used to evaluate the
performance of both OFDM and FBMC in a WiMAX context, i.e. the frame
format is kept as close as possible to WiMAX. From the simulation results it has
been possible to analyze the performance differences between the two systems.
In addition to that the simulator was used as a reference in the validation of the
demonstrator. The transmitter in the demonstrator is implemented in hardware
and operates in real time. The channel emulation and up-conversion to RF is
done using commercially available instruments from Agilent which have been
modified to fit to the task. In the demonstrator receiver the hardware front-end
converts the signal to baseband and digitizes it. The OFDM/FBMC signal
processing is done in near real time on a general purpose computer connected
to the front- end hardware. |
