In this paper; we investigate a new interference mitigation technique to reduce the interference of the primary user caused by the secondary user in CR-MIMO-OFDM systems. More specifically, the interference first is reduced by rough adjustment of the AIC technique and then it is further reduced by fine adjustment of the phase rotation technique. The simulation results show that the proposed interference technique approximately can decrease the interference of the primary user up to 3dB with the same complexity, compared to the conventional AIC technique, for flat fading channels.?????
Keywords:CR-MIMO (cognitive radio); AIC-PR (active interference cancellation - phase rotation) algorithm; interference?
