Abstract(in English) | MIMO communication systems can provide high channel capacity theoretically. However, there is no been sufficient investigation about effects of the imperfection caused by the RF hardware on the MIMO system. In this paper, we focus on the influence of the IQ imbalance on the MIMO communication system. As a result, it is found that the IQ imbalance causes sever degradation into the MIMO communication system. To combat this problem, the new extended channel matrix including the influence of IQ imbalance is introduced. Then the method of IQ imbalance compensation by using the extended channel matrix is proposed in this paper. The validity of the method is investigated by computer simulation. |
