We propose an architecture that incorporates a robust and agile primary user (PU) detection, accompanied by a dynamic OFDM spectrum allocation scheme. By exploiting the capabilities of a 2x2 MIMO PCIe SDR device we are able to maximize the usage of the available spectrum with the minimal PU disturbance.
