In this paper, we evaluate the spectral efficiency of the block diagonalized vector perturbation (BD-VP), vector perturbation (VP) and Tomlinson-Harashima precoding (THP) algorithms over correlated MIMO channels with channel state information (CSI) error. The simulated results show that the VP algorithm has high spectral efficiency than the BD-VP algorithm, but it needs a large computational complexity (CC). Although the BD-VP algorithm is more sensitive to high channel correlation than the THP algorithm for a small signal to noise power ratio (SNR) area, we show that it can utilize the interpolation method with noise component cancellation (NCC) to outperform the THP algorithm and achieve to the system capacity of the VP algorithm over correlation channels. Based on the simulated results, the BD-VP algorithm appears a possible way to realize the large spectral efficiency with a relatively small computational complexity over correlated MIMO channels for the picocell or femtocell systems with CSI error. |
