Reconfiguration management on FPGA platform for cognitive radio

Cognitive Radio (CR) is considered as a promising technique for future wireless communications due to the capability of adapting its behavior to its operating environment. Generally, a management architecture is necessary to efficiently manage the CR features and functionalities. Taking into account of the capability of dynamic partial reconfiguration of FPGA equipment, in this paper, we introduce the implementation of reconfiguration management on a FPGA platform. Based on this kind of reconfiguration management, all reconfigurable radio processing elements (PEs) can be reconfigured efficiently and flexibly, which also makes CR system more practicable and energy-efficient.
