Design Issues and Performance Evaluation of a SDR-Based Reconfigurable Framework for Adaptive OFDM Transmission

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 by Software Defined Radio (SDR) technology based on general purpose hardware. In this paper a reconfigurable framework for adaptive OFDM transmission, named TIGR, is presented. Based on combination of GNU Radio platform and CORBA communication model, TIGR allows for capacity achieving OFDM-based data transmission between two or more network nodes with optimally configured transmission parameters for given system constraints.
