| Abstract(in English) | In this paper, we propose a complexity reduction technique for a higher order multiple input multiple output (MIMO) system by using a block diagonalization (BD) technique in the MIMO receiver. In the wireless communication, the BD technique is well known for canceling the inter user interference (IUI) as a precoding method in a multi-user (MU) MIMO access point (AP). The proposed technique employs the BD technique for a single-user (SU) MIMO receiver's MIMO decoding to reduce the complexity of the higher order MIMO decoder. By using the BD technique, the proposed high order MIMO receiver can decompose perfectly a channel state information (CSI) matrix into sub-matrices of MIMO channel matrix. Therefore the proposed MIMO receiver does not require a higher order MIMO decoder. This means that the hardware circuit area of the proposed MIMO decoder becomes smaller than conventional ones. This paper shows that the proposed higher order MIMO decode technique achieves higher accuracy than conventional MIMO decoder methods such as a Linear minimum mean square error (MMSE), and a lattice reduction aided-MMSE (LRA-MMSE). |
