The platform presented in this work emphasizes the use of software/hardware hetero- geneous devices for flexible multi-RAT architectures. Hardware improvements are mainly focused on Dynamic Partial Reconfiguration (DPR) and especially reconfiguration speed. Management of the reconfiguration process is based on a Hierarchical and Distributed Cognitive Radio Architecture Management (HDCRAM). Some scenarios based on net- work centralized orders or power consumption decentralized orders will be explained. The demonstration is a baseband OFDM transceiver with some emulated white Gaussian noise channel. It functionally consists of three parts: a transmitter, a receiver, and an addi- tive white Gaussian noise (AWGN) channel. The transmitter has two blocks: Mapping and Inverse Fast Fourier Transform (IFFT), and the receiver has also two corresponding blocks: Fast Fourier Transform (FFT) and Demapping. On the hardware point of view, the demonstration is implemented on a laptop and a Zynq platform (device including a hardcore processor and a FPGA).
