In this paper, we investigate the transceiver design for coded multiple-input multiple-output (MIMO) systems assuming channel knowledge at both transmitter and receiver. First we derive an expression of the diversity order of singular value decomposition (SVD) based systems with arbitrary channel coding configurations. Motivated by this analysis, we propose a blockwise design based on uniform channel decomposition (UCD) which utilizes a successive interference cancellation (SIC) receiver. To eliminate error propagation inherent in the SIC structure, the proposed scheme applies the UCD precoder for a pair of subchannels to achieve single-symbol decodable maximum likelihood detection (MLD) instead of the SIC receiver. From the analysis, we demonstrate that the proposed scheme has an enhanced diversity order compared to the SVD scheme by exploiting the feature of the UCD. Also, in the presence of imperfect channel knowledge at the transmitter, we describe an appropriate receive filter design for the proposed scheme. The simulation results show that the proposed transceiver technique outperforms both the SVD scheme and the conventional UCD by about 6dB in 4 by 4 MIMO systems at the spectral efficiency of 12bps/Hz.
