| Abstract |
The investigation and assessment of information theoretic
concepts for wireless resource management in real-world scenarios
requires flexible testbeds with wide range of reconfigurable
parameters. These functionalities are currently offered
only in Software Defined Radio (SDR) technology based on
general purpose hardware.We designed a modular, GNU Radio based
reconfigurable framework which treats OFDM transmission
link as a black box. The control and feedback mechanism
provided by framework allows for optimal assignment of
predefined transmission parameters, (power and rate per subchannel) at the
input and estimation of link quality at the output. High flexibility,
provided by large set of reconfigurable parameters, which are normally
static in real systems, enables implementation and assessment of
different resource allocation strategies for various classes of
system requirements.
Challenges in the design and implementation of resource allocation
strategies and performance evaluation of developed framework components
will be discussed during the talk.
