OFDM-based Dynamic Spectrum Access


M. Zivkovic, D. Auras, R. Mathar,


        Optimal utilization of radio resources (bandwidth,
transmit power) in multicarrier based systems becomes very chal-
lenging due to coexistence of various wireless standards within the
same frequency band. One possible solution is dynamic spectrum
access (DSA) approach that allows several standards or users to
opportunistically share the available spectrum resources without
introducing mutual interference. Proposed demonstration, imple-
mented in GNU Radio framework, enables interference-free coex-
istence of two OFDM-based systems within a common frequency
band with optimally configured transmission parameters for
given system constraints. Furthermore, a highly reconfigurable
framework allows for implementation and evaluation of various
transmission strategies for different DSA scenarios, different
classes of given requirements and various sets of controllable
