As wireless communication services become more prevalent, bandwidth requirement increases dramatically. As such, the concept of cognitive radio (CR) has recently received much attention. In this paper, we present a MIMO-OFDM based CR system capable of dynamically adjusting its system parameters according to spectrum allocation. From system simulation, the proposed transceiver is shown to be a promising solution for CR applications.
